Pennsylvania-Specific Rules

Speed, Right-of-Way & Legal Rules

  • Pennsylvania's maximum posted speed limit is 70 mph.
  • School zone speed limit: 15 mph when the zone sign's lights are flashing.
  • Learner's permit is valid for 1 year once issued.
  • A valid foreign driver's license is honored for up to 1 year from entry, or until it expires — whichever comes first.
  • Reciprocity with France, Germany, Korea, and Taiwan: no road/knowledge retest, but a vision test is still required.
  • Open-bed truck occupied by a passenger: 35 mph speed cap.
  • No child under 18 may ride in an open truck bed, except for farm work, licensed hunting, or an official parade.

DUI Laws & Penalties

  • Zero tolerance: a driver under 21 with BAC .02%+ is penalized under the same "High Rate" tier as a far more impaired adult.
  • General Impairment tier (.08%-.099%), 1st offense: 6 months probation, $300 fine, no license action.
  • High Rate tier (.10%-.159%), 1st offense: 2 days-6 months prison, $500-$5,000 fine.
  • Highest Rate tier (.16%+, refusal, or certain drugs), 1st offense: 12-month suspension + 1-year ignition interlock, even on the first offense.
  • School bus drivers hit the High Rate tier at BAC .02%+, same as under-21 drivers.
  • Commercial drivers hit the High Rate tier at BAC .04%+.
  • ARD (Accelerated Rehabilitative Disposition) is available for a first offense at the High or Highest Rate tiers.
  • Implied Consent: refusing a chemical test means an automatic 1-year suspension, even if later found not guilty of DUI.
  • A refusal plus a prior DUI/refusal stacks to 3 years total (18 months for the refusal + 18 more for the DUI).
  • Under-21 conviction for carrying a false ID: up to $500 fine + 90-day suspension, even if not driving at the time.
  • Under-21 alcohol possession/consumption (no vehicle involved): same 90-day suspension + up to $500 fine.

Defensive Driving

  • Seat belt law: passengers age 8-17 must buckle up in any seating position, front or back.
  • A driver under 18 can't carry more passengers than there are seat belts in the vehicle.
  • Anti-texting law (since March 2012): banned for all drivers, primary offense, $50 fine.
  • Texting ban excludes GPS devices and systems built into the vehicle.
  • Following a horse-drawn vehicle: leave extra room — they often roll backward after stopping.
  • Passing a horse-drawn vehicle or horseback rider: don't speed or blow the horn — it may spook the horse.

Minor & Provisional Licensing

  • Learner's permit minimum age: 16.
  • Under-18 applicants: 65 hours of supervised driving required, including 10 at night and 5 in bad weather.
  • Mandatory 6-month wait from permit issuance before an under-18 applicant can take the road test.
  • Supervising driver: at least 21 (or a parent/guardian/spouse 18+), riding in the front seat.
  • Junior License curfew: no driving 11 p.m.-5 a.m., unless a qualifying adult rides along or a work/volunteer exemption applies.
  • Junior License passenger cap: 1 non-family passenger under 18 for the first 6 months.
  • After 6 months, the cap rises to 3 — unless there's been an at-fault crash or a violation conviction.
  • Mandatory 90-day suspension for a Junior License holder who hits 6+ points or is convicted of 26+ mph over the limit.
  • Junior License converts to regular automatically at 18, or earlier after 1 year if a course, clean record, and parental consent all check out.
  • After 3 failed road tests, an applicant must submit a new learner's permit application.

Parking Rules & Technique

  • No parking within 20 feet of a crosswalk at an intersection.
  • No parking within 30 feet of a flashing signal, stop sign, or yield sign at the roadside.
  • Double parking (stopping on the roadway side of an already-parked vehicle) is prohibited statewide.

Emergency Vehicles, School Buses & Work Zones

  • Stop at least 10 feet from a school bus with flashing red lights and an extended stop arm.
  • The only exception: the opposite side of a physically divided highway — reduce speed and proceed with caution instead.
  • Failing to stop for a school bus: 60-day suspension + 5 points + a fine.
  • Move Over Law: move to a non-adjacent lane, or slow to at least 20 mph under the posted limit if you can't.
  • Move Over Law fines escalate: up to $500 (1st), $1,000 (2nd), $2,000 (3rd+), plus 2 points.
  • A Move Over violation causing serious injury or death: 90-day suspension + up to $1,000 fine (6 months if the victim is an emergency responder or someone near a disabled vehicle).
  • Headlights required in every posted work zone at all times, not just active ones — a $25 add-on fine applies if caught without them.
  • Fines for certain active-work-zone violations, including speeding, are doubled.

Universal Driving Rules

These apply everywhere, not just Pennsylvania — a general refresher, secondary to the Pennsylvania-specific rules above.

Traffic Signs & Signals

  • A single broken white or yellow line means you may pass or change lanes when it's safe and won't interfere with traffic.
  • A red-and-white triangular YIELD sign means slow down and be ready to stop for traffic and pedestrians already in or approaching the intersection.
  • The standard hand signal for stopping is your left arm and hand extended straight down.
  • White arrows painted in a lane show which direction that lane must go — for example, straight-only or right-turn-only.

Road Hazards & Construction

  • A drawbridge is a mechanical bridge that raises or turns to let boat traffic pass, then lowers again for vehicles.
  • Orange signs and cones on the road mean a work zone is ahead — slow down and be ready for workers, equipment, or a lane shift.

Defensive Driving

  • Mirrors alone can't cover your blind spots — turn your head and glance over your shoulder before changing lanes.
  • If a crash is unavoidable, steer toward something that will give way (like bushes) rather than a rigid object like a tree or pole.
  • Look 10-15 seconds ahead of your vehicle so you can react smoothly instead of making sudden last-second moves.
  • Large trucks have bigger blind spots than passenger vehicles — give them extra space.

Intersections and Turns

  • It's illegal to enter an intersection, even on green, unless there's enough space on the other side to get all the way through.
  • Signal continuously for at least 100 feet before making a turn.
  • Entering traffic from a stop, you need a gap large enough to accelerate up to the speed of traffic before merging in.
  • Waiting in an intersection to turn left, keep your wheels straight until you actually turn — angled wheels can push you into oncoming traffic if hit from behind.

Passing

  • On most two-lane roads, passing means briefly using the oncoming lane — only when you can see it's clear far enough ahead.
  • When passing a bicyclist, move as far left within your lane (or into the next lane, if legal) as you safely can.
  • Don't assume a driver you're passing will slow down for you — wait until you can see their whole vehicle in your mirror before pulling back in.
  • You may pass on the right if the vehicle ahead is waiting to turn left.

Highway & Freeway Driving

  • Merge onto a freeway at or near the same speed as the traffic already on it, not slower.
  • The four-second rule: pick a fixed point the car ahead passes, and count at least four seconds before you reach the same point.
  • If you miss your exit, continue to the next one — never back up or cut across the median.
  • A U-turn in a residential district is legal if you can complete it safely, with no vehicles approaching close enough to be a hazard.

Pedestrians, Bicyclists & Children

  • A white cane or guide dog means the pedestrian is blind or low-vision — slow down and be ready to stop, since they may not see you.
  • Where there's no sidewalk, pedestrians should walk facing traffic, as far to the edge of the road as possible.
  • Approach bicyclists, in-line skaters, and non-motorized scooters with extreme caution — give them room and slow down as you pass.

Vehicle Emergencies & Highway Maneuvers

  • If an entrance lane is too short to reach highway speed, stop and wait for a large gap in traffic rather than merging too slow.
  • If a tire blows out, hold the steering wheel firmly and ease off the gas — don't brake hard.
  • Use an acceleration lane to reach highway speed before blending with traffic, unless a stop/yield sign or signal says otherwise.

Fog, Glare & Night Driving

  • To reduce glare from oncoming high beams at night, shift your eyes toward the right edge of your lane instead of looking at the lights.
  • In fog, use low beam headlights — high beams reflect off the fog and reduce visibility further.

Weather & Road Surface Conditions

  • If your car starts to skid, steer in the direction you want the front wheels to go.
  • Driving slower reduces hydroplaning risk by giving your tires more chance to channel water away.
  • Roads are most slippery in the first 10-15 minutes of a rainstorm, before rain washes oil and grime off the pavement.

Trucks, Motorcycles & Slow-Moving Vehicles

  • The extra space in front of a large truck is there because trucks need much more distance to stop — don't cut into that gap.
  • If you see an animal on or near the road, slow down and be ready to yield rather than swerving suddenly.
  • Leave at least 4 seconds of following distance behind a motorcycle — more than the usual car-following gap.
  • An orange-and-red triangular emblem on the back of a vehicle marks a slow-moving vehicle, like farm equipment.

Vehicle Handling & Road Conditions

  • Reduce your speed before and during a turn — taking a turn too fast makes the vehicle harder to control.
  • On slick roads, take turns more slowly than you would on dry pavement.
  • Signal early — well before you actually change lanes or pass — so other drivers have time to react.
  • Turn your headlights on in poor visibility, and as routine about a half hour after sunset and before sunrise.

Alcohol and Other Drugs

  • Your BAC doesn't depend on what kind of alcohol you drink, your body type, or how well you can "hold your liquor."
  • Combining drugs — including many over-the-counter or prescription medications — with alcohol multiplies impairment and crash risk.
  • As alcohol builds up in your bloodstream, it slows your reaction time, judgment, and coordination.
  • Chemical tests (blood, breath, urine, or saliva) are used to measure blood alcohol content.
