Track Day Basics

First-timer's guide to HPDE track days and SCCA autocross: how the day runs, flags, passing, car prep, and a quiz.

First rule: every club and every track runs things a little differently. This page explains the common pattern and shows where the big clubs differ. At your event, the drivers' meeting and the event's own supplemental rules win over anything here.

The clubs compared: NASA (National Auto Sport Association, rulebook "CCR" 2026.3), SCCA (Sports Car Club of America: Track Day Rules 2026, which also cover Track Night in America, and the Solo autocross rules 2026), and a PCA region (Porsche Club of America, Northeast Region's 2026 Palmer event pack). Numbers like CCR 6.3 point to the rule.

Already done a few days? The next step is Advanced Track Driving: grip, the line, braking, setup and data.

What an HPDE is

HPDE = High Performance Driver (or Driving) Education. You drive your own car on a real race track, in a group of cars of similar experience, with an instructor beside you while you're new. Also called a DE, track day, open track or "school".

  • It is not a race. No official timing, no finishing order, no trophies. NASA calls HPDE "non-competition groups" CCR 3.2; SCCA says track days "are not competition" TD Rules I.1.2; PCA says it is not racing or preparation for racing.
  • Why it exists: to learn car control and the limits of you and your car in a controlled place, with corner workers, an ambulance and tow crews on hand, instead of finding out on a public road.
  • Cars run together (unlike autocross), so traffic, mirrors and passing are a big part of the skill.

Car version: it's the difference between a test drive around the block and putting a car on a dyno with a tech watching every gauge. Same car, but now the conditions are controlled and someone is watching for trouble.

How the day runs

  1. Gate and waiver. Everyone who enters, guests included, signs the waiver and gets a wristband CCR 1.4.4–1.4.5; PCA.
  2. Registration. Show your driver's licence and club membership (NASA or SCCA; a one-weekend SCCA membership counts TD Rules II.1). Pick up your car number and schedule. Some events give you a work assignment too (PCA does).
  3. Tech inspection. An inspector checks the car and your helmet (list below). NASA lets you tech at an approved shop beforehand and bring the form, or tech at the track CCR 11.2. Fail tech and you don't go out.
  4. Drivers' meeting (mandatory). Passing zones, flag station locations, the pit-out blend line, the pit-in point, the schedule, and anything special about this track. This is where the real rules for the day come from.
  5. Novice classroom. First-timers usually get extra classroom time: flags, the line, what the instructor will do.
  6. Meet your instructor or coach and get to grid (also called pre-grid or staging) a few minutes before your group's session.
  7. Sessions. Usually several sessions per group across the day. The first lap or two are often warm-up laps with no passing.
  8. Checkered flag, cool-down lap, pit in. Wave to each corner station on the cool-down lap (NASA asks for this CCR 8.3).
  9. Debrief. Talk through the session with the instructor right after, while it's fresh. NASA builds this in as a "classroom/clipboard session" after every session CCR 10.2.5.

Run groups and instructors

Drivers are grouped by experience so speeds and skills in each group are similar. Passing rules loosen as groups get more experienced.

ClubGroup namesHow you move up
NASAHPDE 1, 2, 3, 4 (then Time Trial or racing)An instructor signs you off. NASA's progress record is the HPDE Passport CCR 10.2.3.
SCCA Track Day / Track NightNovice, Intermediate, AdvancedSuggested guidelines, not licences TD Rules II.2: Novice = never driven on track with flags and point-bys (even experienced autocrossers may be put here); Intermediate = knows every flag, consistent, gives point-bys on time; Advanced = lots of track time, gives and takes point-bys anywhere.
PCA (Northeast Region, 2026)Colour names: Green, Yellow, Blue, White, Black, RedInstructor sign-off to drive "solo" (without an instructor in the car).

What the instructor does

  • At NASA and PCA events, a novice's instructor rides in the passenger seat, usually with an in-helmet intercom, and coaches the line, braking points and traffic.
  • SCCA track days (including Track Night) allow coaching from inside the car, from posts around the track, or from a central spot; novices get classroom time, regular debriefs, and are watched by the Novice Coach or helpers whenever they're on track TD Rules App. C 8.1.E. Ask whether in-car coaching is offered.
  • May drive your car first with you as passenger to show the line. At NASA, an instructor's own car has a big "X" on the sides and back CCR 10.3.3.
  • Because an instructor rides along, the passenger seat and belts must be as good as the driver's TD Rules IV.2.1.1.C.
The fastest way to improve, and the safest, is to do what the instructor says even when it feels slow. Their job is to keep you inside a margin you can't see yet.

Passing and point-bys

In HPDE, the car in front decides when you pass. It gives a point-by: an arm out of the driver's window pointing to the side the following car should pass on. No point-by, no pass.

"Pass me on the LEFT" arm straight out the window "Pass me on the RIGHT" arm out and over the roof Seen from behind; US cars, driver on the left.

The common rules

  • Only in passing zones for your group, announced at the drivers' meeting. Typical progression (SCCA's suggestion TD Rules V.3.3): Novice on the longest straights only, Intermediate in designated zones, Advanced anywhere, always with a point-by.
  • One point-by for each car. If two cars are behind you, point twice (PCA).
  • After you point, make room: stay on your line and ease off a little so the pass finishes quickly TD Rules V.3.2. PCA prefers the car being passed to stay on the normal line.
  • Finish before the braking zone. If the pass isn't done by the end of the zone, the passing car backs off and tries next time. Never dive past at the end of a straight.
  • The passer is responsible for a safe pass and must be sure the other driver has seen them CCR 6.3.6.
  • Never under a yellow flag, even if someone waves you by CCR 6.3.3, 6.3.5. Exception: a car that is clearly broken and pulling off may be passed CCR 6.3.4.
  • Declining a pass: stay visibly behind the car, not in its blind spot, so it knows you aren't coming (PCA).
  • Don't lead a train. If cars stack up behind you, it's your job to let them by, or to pit in and go back out in a gap (PCA). Being caught in the corners means the other driver is quicker overall, even if your car has more power on the straights.
Where clubs differ: NASA's rulebook leaves passing zones to each event CCR 6.3.1; many NASA regions limit HPDE 1 and 2 to set straights with a point-by and loosen it for higher groups (regional practice: check yours). Some events allow drivers who can't point to use the turn signal, marked with bright tape, and cars with window nets may point from inside TD Rules V.3.2.1–2. The blue flag (below) tells you someone wants by: give a point-by when it's safe.

Pit in and pit out

Coming in (pit in)

  1. Signal early, on the straight before pit entry, so cars behind expect you to slow.
    SCCA: arm raised out the window with a fist TD Rules V.3.4. NASA: arm raised straight up, fingertips to the sky CCR 8.1. Either way: raised arm = "I'm slowing or coming in".
  2. Stay off the racing line as you slow, on the side the drivers' meeting gave for pit entry.
  3. Obey the pit-lane speed limit. It's set per track (Palmer's hot pits: 20 mph). NASA treats the hot pits as part of the race track, speed limit or not CCR 1.2.4.
  4. Paddock: walking pace. NASA's paddock limit is 5 mph CCR 5.1; people and kids are everywhere.

Going out (pit out)

  1. Wait for the pit-out marshal's signal (a worker at the end of pit lane controls who goes out, and when).
  2. Stay on the blend side of the track until the blend line ends. The blend line is painted at pit exit to keep joining cars out of the way of cars at speed. Which side it's on depends on the track: at Palmer (clockwise) you stay right until the apex of Turn 14, and leaving the blend area early gets a black flag (PCA 2026 pack).
  3. Warm up. Cold tires and brakes have less grip; build up over the first lap or two.

After the checkered flag

  • Slow down, keep a gap, signal, and come in at the next pit entry. The cool-down lap also cools the brakes.
  • Passing on the checkered lap differs: NASA keeps the session's passing rules during the checkered lap CCR 7.8; PCA Northeast Region allows no passing under the checkered flag. Follow your event.
  • Common advice: after a hot session, don't set the parking brake on very hot brakes if you can avoid it (chock the wheels or leave it in gear). Clamping a glowing-hot pad on one spot of the rotor can leave a pad-material imprint you feel as a vibration later.

On-track etiquette and safety

  • Mirrors on every straight. You can't give a point-by to a car you haven't seen.
  • Be predictable. Drive the same line lap after lap. Sudden moves off line, or braking early with no warning, cause crashes.
  • Flags come first. Know the station locations (some events show a standing white flag at every station on the first lap to point them out TD Rules V.2.1.5) and look at every station every lap.
  • Windows: NASA requires both front side windows fully open in HPDE CCR 6.2 (for hand signals, and so a worker can reach in). Other clubs set their own rule: ask.
  • Stopping on track is forbidden except in a real emergency (medical, mechanical failure, fire, damage), and you may not stop to help another car CCR 6.5.
  • Broken down? Get off line and off the track somewhere safe, away from dry grass (a hot exhaust can light it) CCR 6.5.1. Stay in the car, belted, helmet on unless it's on fire, until an official tells you otherwise TD Rules V.5.2; PCA; CCR 6.9 after a crash, and give the corner workers a thumbs-up if you're OK.
  • Body contact is treated very seriously at every club; NASA can eject you permanently CCR 6.8.
  • Never drive backwards on the track unless an official tells you to CCR 6.6.
  • No alcohol while there's driving to do. NASA bans it for participants at the event CCR 4.7; SCCA bans it until your group's sessions are done TD Rules I.1.4.1.

How warnings add up (NASA)

For HPDE 1–3, NASA counts these as offences: body contact, passing under yellow or red, passing in a no-passing zone, driving the wrong way, hitting barriers, spinning, four wheels off, repeated two wheels off, and over-aggressive driving or passing. First offence of the day: warning. Second: out for the rest of that session. Third: out for the day CCR 2.6.4.1.

Off-track excursions and spins

"Two wheels off": don't jerk it back

You've run wide and the right-side tires are on the grass or dirt. The instinct is to yank the wheel back toward the track. Don't.

  • Why: the tires on grass have little grip, the ones on pavement have a lot. A big steering input lets the pavement tires bite suddenly while the others slide, and the car snaps sideways across the track, often into the wall on the other side. That's how a harmless excursion becomes a crash.
  • What to do: keep the steering steady and fairly straight, ease off the throttle smoothly (don't stab the brakes), let the car slow down, and come back on gently at a shallow angle only when it's slow and you've checked for traffic. If it's going wrong anyway, ride it out straight.

"In a spin, both feet in"

  • Once a spin can't be caught, push the brake and the clutch all the way down (automatic: just the brake, hard).
  • Why the brake: full brake makes the car slide along a straight, predictable path, so other drivers and workers can tell where it's going, and it sheds speed. (With ABS, as on most modern cars, the wheels keep turning, but full brake still slows the car and keeps its path predictable.) Why the clutch: the engine keeps running so you can drive away, and the drivetrain isn't shock-loaded.
  • When it stops: stay put, look for traffic, and wait for a corner worker to wave you back on (NASA asks you to get a worker's help CCR 6.7).

Then come in and talk

Where clubs differ: NASA: after any spin or off-track excursion, pull into the hot pits right away so officials can check the car and talk to you CCR 6.7. SCCA: after four wheels off or a "significant loss of control" you may be asked to self-report to the pits for a chat with the session's coach (drivers who don't may be black-flagged); repeated two-wheel-offs can earn a black flag TD Rules I.3.3. PCA Northeast Region: two or four wheels off, a spin or contact gets a black flag; don't wait for it, come in "Two Spin Rule".

SCCA's track-limit rule for reference: keep at least part of one tire on the marked track at all times TD Rules I.3.2.

Car prep and tech inspection

A track day takes a car from street duty to maximum braking, cornering and heat for 20 minutes or so at a time (SCCA sessions shouldn't run past 20 TD Rules App. C 7.6). Tech checks the things that fail first. Required = on the tech sheets below; Recommended = widely advised.

ItemWhat and why
Brake fluid ReqClean and full; SCCA recommends DOT 4 TD IV.2.1.3.B. Why: track braking heats the fluid; if it boils, vapour bubbles compress and the pedal goes soft or to the floor. Brake fluid absorbs water over time, which lowers the boiling point. Federal minimums (FMVSS 116): DOT 3 boils at 205 °C (401 °F) new, 140 °C (284 °F) "wet"; DOT 4 230 °C (446 °F) new, 155 °C (311 °F) wet. Rec Fresh high-temperature DOT 4 and a bleed before the event.
Brake pads, rotors ReqSCCA guideline ("should"): pads at least 50% left at the start and never past 85% worn during sessions; rotors without cracks TD IV.2.1.3. Pads wear many times faster on track than on the street.
Tires ReqGood condition, enough tread, correct speed rating; no cords, bubbles or damage TD IV.2.1.4; CCR 11.4.2. Check pressures before and after every session (track pressures rise a lot as tires heat).
Wheels, lug nuts ReqAll present and torqued to spec TD IV.2.1.4.B; no cracked wheels; hubcaps and loose trim off. Rec Re-check torque during the day (PCA tells drivers to check it throughout the event): heat cycles and new wheels can let nuts lose clamp. Use a torque wrench, not an impact gun.
Loose items ReqInterior and trunk emptied, including floor mats not held by clips TD IV.2.1.2. At 1 g of braking a water bottle under the brake pedal is a real danger, and anything loose becomes a missile in a crash.
Seats and belts ReqFactory (or better) seats securely mounted; belts with at least 3 mounting points TD IV.2.1.1. NASA doesn't allow lap belts alone and only allows certain 4-point belts CCR 11.3.2.
Battery ReqHeld down solidly (not with bungee cords), positive terminal covered TD IV.2.1.6.C; CCR 11.4.9.
Fluids and leaks ReqLevels correct, caps tight, no leaks; belts and hoses good TD IV.2.1.6. A leak on track puts oil under the next car's tires.
Suspension, steering, bearings ReqNo wheel-bearing play, good ball joints, no excess steering play, no leaking shocks TD IV.2.1.5. A tech checks this like a pre-alignment inspection: grab the tire at 12 and 6, then 3 and 9.
OthersAt least one working brake light (SCCA) or two (NASA: two red brake lights visible from 300 ft) TD IV.2.1.3.C; CCR 11.4.18; a rear-view mirror; car number on both sides (NASA) CCR 11.4.14–15; NASA's "50/50 rule": the car must look undamaged at 50 mph from 50 feet CCR 11.4.1; camera mounts solid. Rec Tow hooks front and rear, and an oil change if it's due.

Helmet and clothing

The helmet label is what tech checks. Labels name a standard and a year; clubs accept a list of recent ones.

Club / rulebookHelmets accepted
SCCA Track Day / Track Night (2026)Snell SA2020, M2020, EA2016, SA2015, SA2010, SAH2010, M2015, M2010; SFI 31.1 and 41.1 (2010, 2015, 2020); FIA 8859-2015, 8860-2010, 8860-2004 TD Rules II.4.1
SCCA Solo autocross (2026)A longer, newer list including Snell SA2025, M2025D and M2025R (see the Autocross tab) Solo 4.3.1
NASA HPDE (2026.3)Snell 2010 (SA2010, M2010) or newer, or ECE 22.06 or newer, car or motorcycle CCR 11.3.1
Other clubsSome accept M (motorcycle) helmets only with a fire-resistant balaclava (e.g. CACC 2025 HPDE rules)
  • SA vs M: Snell SA ("Special Application") helmets are built for car racing: they include fire-resistance testing that M (motorcycle) helmets don't. Rec If you're buying one, buy SA (new ones are SA2025 now). SA2025 is on the 2026 Solo list and meets NASA's rule; SCCA's 2026 Track Day list was written before SA2025 and only names up to SA2020, so check with the organiser before a Track Day or Track Night.
  • A plain DOT-only motorcycle helmet is not on these lists. DOT is the US legal minimum for street riding, not a track standard.
  • Fit: snug, no rocking, chin strap fastened. Helmets age: clubs drop older standards over time, which is why the year matters.
  • Clothes: NASA wants cotton (non-synthetic), no tank tops, no open-toed shoes CCR 11.3; SCCA recommends natural fibres and requires shoes covering the whole foot TD Rules II.4.2. Why cotton: synthetics melt onto skin in a fire. Thin-soled shoes give the best pedal feel.

What to bring

Required

  • Driver's licence and club membership
  • Approved helmet (or reserve a loaner if the club offers one)
  • Tech form, if your club uses one, filled in
  • Car prepared per the tech list, empty inside
  • Proper clothes and closed shoes
  • Boards or plates for jack stands (NASA requires something under loaded stands to protect the asphalt) CCR 5.1

Recommended

  • Tire pressure gauge (the same one every time)
  • Torque wrench and lug-nut socket
  • A spare litre of brake fluid and a quart of oil
  • Painter's tape for numbers (if the club doesn't supply them)
  • Water, food, sunscreen, hat, rain jacket: you'll be outside all day
  • Fuel plan: the track may not sell fuel CCR 5.1
  • Water jug for fuel spills (NASA requires water on hand) CCR 5.1

Optional

  • Folding chair, small tarp or bin to hold everything you took out of the car
  • Jack, jack stands, basic hand tools
  • Notebook: tire pressures, what the instructor said, one thing to work on next session
  • Camera (solidly mounted) or data logger; see Advanced Track Driving for using data
  • Tire pyrometer (measures tread temperature; explained on the Advanced page)
  • Driving gloves
Cameras and data loggers: clubs mostly care that everything is mounted solidly and no cable is near the pedals. NASA leaves camera mounts unrestricted CCR 11.4.16.
