Stop signs (8-sided)
At a stop sign, wheels must come to a complete stop behind the stop line or crosswalk. Then look for crossing traffic and pedestrians in all directions and yield before proceeding.

Traffic Signals

Solid Red

Full stop. Wait behind stop line until green. Right-on-red allowed unless a sign prohibits it.

Solid Yellow

Warning — the light is about to turn red. Stop if you safely can.

Solid Green

You may go — yield to pedestrians and vehicles already in the intersection.

Flashing Red

Come to a complete stop. Then proceed when safe, yielding right-of-way.

Flashing Yellow

Slow down and proceed with caution. Be prepared to stop.

Green Arrow signal
Green Arrow

Turn in the direction of the arrow after yielding to pedestrians and traffic.

Red Arrow signal
Red Arrow

Do not enter the intersection in that direction.

Yellow Arrow signal
Yellow Arrow

Slow down and proceed in the direction of the arrow with caution.

A police officer directing traffic
Overrules any traffic light or sign and must be obeyed.

Pavement Markings

Line color tells you the direction of traffic; line style tells you whether you can cross it.

Same-direction traffic lanes. Lane changes allowed when safe.
Same-direction traffic. Lane change / pass prohibited.
Opposing-direction traffic. You may pass when safe.
Do not pass when the solid line is on your side.
Never cross to pass (double solid yellow).
Edge lines
White edge line marks the right edge of the road and both edges of one-way roads. Yellow edge line marks the left edge of one-way roads.
Shared center turn lane
A center lane marked with broken yellow and solid yellow lines is for left turns only from either direction — never for through traffic or passing.

Speed Limits

Posted limits are the maximum for ideal conditions. You must reduce speed for weather, traffic, road, or visibility conditions.

School zone
Posted limit 10 MPH below the usual limit, from 45 minutes before opening to opening, and from closing until 45 minutes after closing.
Interstate minimum
Minimum speed is 45 MPH unless road or weather conditions make that speed unsafe.

Right-of-Way

Right-of-way rules tell you who should yield — not who can force their way through. Never assume another driver will follow them.

Uncontrolled intersection

The vehicle on the LEFT yields to the vehicle on the RIGHT (RSA 265:28).

Turning left

A left-turning driver must yield to oncoming traffic within the intersection or close enough to be a hazard (RSA 265:29).

Four-way stop

First to arrive goes first. If two arrive together, the one on the right goes first.

Entering a highway

Drivers entering from a driveway or ramp must yield to traffic already on the public highway.

Pedestrians

Always yield in marked crosswalks, at unmarked intersection crossings, and on sidewalks/driveway crossings.

Emergency vehicles

Yield to any emergency vehicle using lights or siren — pull to the right and stop until it passes.

Roundabouts

Yield to all traffic already in the roundabout. Enter when there is an adequate gap.

Funeral processions

Let vehicles following a hearse with headlights on pass as a group.

Visually-impaired pedestrians
NH law requires drivers to come to a complete stop whenever a pedestrian carrying a white cane (red tip) or using a guide dog is attempting to cross the road.

Following & Stopping

4
seconds minimum
Following distance between your vehicle and the one ahead, under ideal conditions.

Increase following distance:

  • On slippery / wet roads
  • When following large trucks, buses, or trailers
  • At night, in fog, or bad weather
  • When following vehicles that must stop at railroad crossings
  • Behind a motorcycle (at least 4 seconds)
  • Whenever visibility is reduced

Speed matters — a lot
When you double your speed, your stopping distance becomes approximately 4× greater.

Turning, Passing & Lane Use

100 ft
Signal before a turn
500 ft
Signal on highways (lane change / exit)

Right turn

Turn from the rightmost portion of the rightmost lane. Don't swing wide to the left first.

Left turn

Turn from the leftmost portion of your lane. Yield to oncoming traffic.

Turning into which lane?

Turn into the lane closest to you going in your direction of travel.

Missed your exit?

Continue to the next exit. Never stop, back up, or turn around on a divided highway.

Do NOT pass
When oncoming traffic is approaching, when view is blocked by a curve or hill, at intersections, or before a railroad crossing or bridge. Never pass on the shoulder — paved or not. The left-most lane on a multi-lane road is for passing slower vehicles.

Sharing the Road

Bicyclists

  • • Treated as vehicles; same rights and responsibilities as drivers.
  • • Pass with at least 3 feet of clearance at 30 MPH or less; +1 ft for every 10 MPH above 30.
  • • Ride in the same direction as traffic (right side).
  • • Yield when a bike lane or path crosses a road.

Motorcycles

  • • Entitled to a full lane — never share a lane with a motorcycle.
  • • Keep at least a 4-second following distance.
  • • Many motorcycles don't auto-cancel turn signals. Confirm the rider is actually turning.
  • • Helmets are required for riders and passengers under 18.

Large trucks — the "No-Zone"

  • • Huge blind spots on both sides, front, and rear.
  • • Rear No-Zone can extend up to 200 ft.
  • • A loaded truck at 55 MPH needs ~335 ft to stop — never cut in front.
  • • If you can't see the driver in their mirrors, they can't see you.

Pedestrians & horses

  • • Pedestrians have right-of-way in all crosswalks and on sidewalks.
  • • Walking on a road with no sidewalk — walk on the left, facing traffic.
  • • Wear light-colored clothing or carry a light at night.
  • • Near a horse: slow down, pass with caution, never honk or rev the engine.
Slow-moving vehicle emblem
The reflective orange/red triangle means the vehicle travels less than 25 MPH (farm equipment, animal-drawn vehicles, construction).

Emergency Vehicles & Police Stops

When an emergency vehicle approaches
Pull immediately to the right side of the road and stop until the emergency has passed. Do not block intersections.
500 ft

If you are pulled over by police

  1. Come to a complete stop and put the vehicle in park.
  2. Remain in the vehicle unless asked to exit.
  3. Turn off engine; turn on hazards (and interior lights at night).
  4. Keep safety belt on; place hands on the steering wheel; limit movements.

Jessica's Law

All snow and ice must be removed from the vehicle before driving on NH roadways.

Securing a load

Nothing may slide, shift, fall, sift onto the road, or become airborne. Failing to secure = fine.

Night & Adverse Conditions

Headlight requirements
Required from ½ hour after sunset to ½ hour before sunrise, and whenever rain, snow, or fog reduces visibility below 1,000 ft.

High beams

Use when no oncoming traffic. Dim for all approaching traffic. Don't stare at oncoming lights — look at the right edge of the road.

Fog, rain, snow

Use LOW beams. High beams reflect off moisture and reduce visibility.

Night following distance

Add at least 1 extra second; 2 extra seconds on unfamiliar roads at night.

Hydroplaning

Happens when tires ride up on pooled water. Prevent by slowing in rain and keeping tires properly inflated with good tread.

Slippery roads & curves
Reduce speed at the first sign of rain, snow, sleet, or ice. Slow down before entering a curve — never brake hard once in it.
Stuck in a blizzard?
Stay with the vehicle. Tie a red cloth to the antenna or door (white in non-snow emergencies).

Vehicle Emergencies

Tire blowout

Grip the wheel firmly; keep going straight. Ease off the accelerator — do not slam the brakes. Pull off when safe.

Stuck accelerator

Keep eyes on the road. Shift into NEUTRAL. Brake firmly. Pull off road, then turn off engine.

Brake failure

Engage the parking brake slowly (to avoid rear-wheel lockup). If that fails, turn off engine and find a safe place to stop.

Skid

Ease off the accelerator. Steer in the direction the rear of the vehicle is sliding. Don't slam on brakes.

Headlights fail

Try turn signals or hazards. Pull off the road as quickly and safely as possible.

Engine dies while driving

Keep a firm grip on the wheel (steering may get heavy). Brake gently and pull off the road.

Breakdown checklist
Turn on hazards, get off the road, place flares or reflectors 200 ft in front and behind (if you have them), call for help, stay with the vehicle unless it's in a hazardous location.

Accidents & Reporting

$1,000
Damage threshold
Accident must be reported to DMV
15 days
Report deadline
From the date of accident

At the scene

  1. Stop. Move the vehicle off the road if possible.
  2. Call 911 if anyone is injured.
  3. Give aid — but don't move injured people unnecessarily.
  4. Exchange names, addresses, license numbers, plate numbers, vehicle info, and insurance.
  5. Get witness contact info.
Railroad crossings
When a train is approaching, stop behind the stop line or between 15 and 50 feet from the nearest rail. Do not cross until lights stop flashing AND you have a clear view both ways.
Financial responsibility
NH does not mandate insurance — but if you're at fault in an uninsured accident, you're personally responsible for all damages and medical bills. DMV can suspend your license until settled; you may be required to carry SR-22 insurance for years.
