A motorcycle is a full-size vehicle with the same rights and responsibilities as any other. Its small profile makes it hard to see and hard to judge for speed and distance. Most motorcycle crashes with cars are caused by the car's driver, not the rider.

Know the rule

Don't crowd motorcycles or take their right-of-way. Anticipate a rider's moves: potholes and other minor annoyances for you are major hazards for them.

About 4,000

Motorcycle crashes on PA roads each year; half involve another vehicle, and almost two-thirds of those are caused by the other driver

Handbook p. 2 ↗

Know the rule

By law you must allow a motorcycle or moped one complete lane. Do not share the lane, even if it looks wide enough.

Handbook p. 60 ↗
4 seconds or more

Following distance behind a motorcycle or moped, the same as other vehicles; increase it in bad road or weather conditions

Handbook p. 60 ↗

Know the rule

In dry conditions motorcycles can stop more quickly than cars, so leave extra room.

Handbook p. 2 ↗

Know the rule

Don't trust a motorcycle's flashing turn signal: it may not cancel itself, and riders forget. Don't pull out in front of a motorcycle or moped until you see it actually turning.

Handbook p. 60 ↗
Nearly 40%

Of motorcycle crashes involving another vehicle, the share caused by the other vehicle turning left in front of the rider

High-risk situations for motorcyclists

  • Left turns: most motorcycle/vehicle crashes happen at intersections
  • Your blind spot: check mirrors and blind spots before changing lanes and at intersections
  • Road hazards: potholes, gravel, wet surfaces, pavement seams, railroad crossings, grooved pavement
  • Wet or icy roads, which impair braking and handling
  • Strong winds and gusts from large trucks, which can push a motorcycle across a lane
  • Vans and trucks that hide a motorcycle, so it seems to appear from nowhere
Handbook p. 2 ↗

Know the rule

Signal before changing lanes or merging so a rider can anticipate traffic and find a safe lane position.

Handbook p. 2 ↗

Put it into practice

You're waiting to turn left and an oncoming motorcycle is signaling right. Wait. Its signal may be left on by mistake, and a car turning left in front of a motorcycle causes nearly 40% of these crashes. Go only once you see it actually turning.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

According to the handbook, most vehicle/motorcycle crashes happen where?
  1. On rural back roads
  2. At intersections
  3. In parking lots
  4. On limited-access highways

Answer: At intersections

Most motorcycle/vehicle crashes occur at intersections, often from left-turning vehicles.

Handbook p. 60 ↗
Why should you not assume a motorcycle is turning just because its signal is flashing?
  1. Motorcycles are not required to signal
  2. Riders signal only when changing lanes
  3. Their signals may not cancel automatically
  4. Riders often signal the wrong direction

Answer: Their signals may not cancel automatically

Motorcycle turn signals may not cancel automatically, so a flashing signal doesn't guarantee a turn.

Handbook p. 60 ↗
How much of a traffic lane must you allow a motorcyclist?
  1. Half a lane, sharing the rest with a car
  2. Only the shoulder
  3. One-third of a lane
  4. A complete lane

Answer: A complete lane

By law, motorcyclists are entitled to use one complete lane.

Handbook p. 60 ↗
Motorcyclists are legally entitled to use a full traffic lane.
  1. True
  2. False

Answer: True

Drivers must allow motorcyclists a complete lane rather than sharing it.
