Bicycles and mopeds are small, slow and easy to overlook, and most collisions with them happen at intersections. On public roads, riders have the same rights and responsibilities as motor vehicle operators.

Driving near bicycles and mopeds:

  • Scan intersections for them and give them the same consideration as any other vehicle
  • Turning right onto a main road? Look right for wrong-way cyclists on the road or sidewalk
  • Following a cyclist and turning right? Slow down and stay behind until you can turn
  • Turning left? Yield to oncoming cyclists unless you're sure you'll clear the intersection first
  • Expect changes in speed or position for manhole covers, tracks, drain grates, debris or wind
  • Check for cyclists before opening your door into a traffic lane or bike lane
Handbook p. 33 ↗

Know the rule

When passing, give bicycles and mopeds a full lane width; don't squeeze past. If the lane is too narrow to share, wait for a clear stretch of road.

Handbook p. 33 ↗

Bicycle lane

A part of the roadway marked by striping for bicycles. You may cross it to turn or to enter or leave the road, but you must yield to bicyclists in it.

Handbook p. 33 ↗

Know the rule

Riders must ride with traffic, never against it. When slower than traffic, ride as near the right side as is safe, leaving space from hazards like ditches, gutters, sand and gravel.

Handbook p. 34 ↗

Riders may move toward the middle or left of the lane when:

  • Making a left turn
  • Avoiding hazards
  • The lane is too narrow to share with another vehicle
  • Going straight where there's a right-turn-only lane
Handbook p. 34 ↗

Know the rule

On a one-way street, bicyclists may ride as far left as is safe. Always check traffic and signal before changing position.

Handbook p. 34 ↗

Know the rule

Mopeds may not be ridden on any part of the federal interstate highway system.

Handbook p. 34 ↗

Know the rule

State law doesn't require bicycle or moped riders to wear a helmet, but a safety-certified helmet can prevent serious head injury or death.

Handbook p. 34 ↗

Know the rule

Riders should leave three to four feet when passing to the left of parked or moving vehicles. In heavy traffic, less proficient cyclists may wait near the curb for a safe gap.

Handbook p. 34 ↗

Know the rule

For teen and adult bicyclists, riding in the street with traffic is far safer than riding on the sidewalk.

Handbook p. 34 ↗

Put it into practice

You're waiting to turn right onto a main road and looking left for a gap. Before you go, look right too: a wrong-way cyclist on the sidewalk could be heading into your path.

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.

Where do most collisions between motor vehicles and bicycles/mopeds happen?
  1. On highways
  2. In parking lots
  3. On rural gravel roads
  4. At intersections

Answer: At intersections

Most collisions with bicycles and mopeds happen at intersections, where they are easy to overlook.

Handbook p. 33 ↗
You are turning right onto a main road and looking left for traffic. What hazard should you also watch for?
  1. Wrong-way bicyclists approaching from your right
  2. Traffic approaching from behind
  3. Only oncoming cars
  4. Pedestrians on the far sidewalk

Answer: Wrong-way bicyclists approaching from your right

Crashes with wrong-way bicyclists often occur when a driver only looks left before turning right, missing bicyclists approaching from the right.

Handbook p. 33 ↗
How much lateral space should you leave when passing a bicyclist?
  1. At least two feet
  2. A full lane width
  3. At least three feet
  4. Half a lane width

Answer: A full lane width

Give bicycles and mopeds a full lane width when passing; do not squeeze past them.

Handbook p. 33 ↗
You must yield to bicyclists in which type of lane?
  1. Only a bike path off the roadway
  2. A center turn lane
  3. A bicycle lane
  4. A parking lane

Answer: A bicycle lane

You must yield to bicyclists in a bicycle lane; you may cross it only when turning or entering/leaving the roadway.

Handbook p. 33 ↗
Does Missouri state law require bicycle riders to wear a helmet?
  1. Yes, always required by state law
  2. Only for riders under 12
  3. No, but strongly recommended
  4. Only on highways

Answer: No, but strongly recommended

State law does not require a helmet for bicycle/moped riders, but wearing a safety-certified helmet can prevent serious injury.

Handbook p. 34 ↗
Missouri law allows mopeds to be ridden on any part of the federal interstate highway system.
  1. True
  2. False

The law does not allow riding a moped on any part of the federal interstate highway system.
