Helmet law, mirror habits, night riding and group formations round out safe motorcycling. Several of these have exact numbers the test can ask about.

Know the rule

New Mexico law requires all motorcycle drivers and passengers under 18 to wear a helmet. Wearing one is recommended for all riders and passengers.

Handbook p. 40 ↗

For the most protection, the helmet should:

  • Meet U.S. Department of Transportation (DOT) standards (ANSI or Snell labels add assurance)
  • Fit snugly, all the way around
  • Have no obvious defects such as cracks, loose padding or frayed straps
Handbook p. 40 ↗

Know the rule

Keep the helmet securely fastened whenever you ride.

Handbook p. 40 ↗

Check your mirrors especially:

  • When stopped at an intersection: watch cars coming up from behind
  • Before you change lanes: make sure no one is about to pass
  • Before you slow down: the driver behind may not expect it
Handbook p. 40 ↗

Convex mirrors

Rounded mirrors on most motorcycles. They give a wider view behind than flat mirrors, but make cars seem farther away than they are.

Handbook p. 40 ↗

Know the rule

Practice with convex mirrors until you judge distance well, and even then allow extra distance before changing lanes.

Handbook p. 40 ↗

At night:

  • Reduce speed, especially on unfamiliar roads
  • Open up a three-second following distance and allow more room to pass and be passed
  • Use your high beam whenever you're not following or meeting a car
  • Wear reflective materials and be flexible about lane position

Staggered formation

Staggered formation
RiderPosition
LeaderLeft side of the lane
Second1 second behind, right side
ThirdLeft side, 2 seconds behind the first
Fourth2 seconds behind the second rider
Handbook p. 41 ↗

Know the rule

When passing in formation, go one at a time. The leader passes, returns to the left position and keeps passing speed; the second rider moves up to the left position, passes, then returns to the right position.

Handbook p. 41 ↗

Know the rule

Don't have the leader move to the right side after passing; it encourages the next rider to cut in before there's enough space.

Handbook p. 41 ↗

Know the rule

Switch to single-file when riding curves, turning, or entering or leaving a highway.

Handbook p. 41 ↗

Put it into practice

Your group of four approaches a winding canyon road. Switch from staggered to single-file formation through the curves, and return to staggered once the road straightens.

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.

Who is required by New Mexico law to wear a motorcycle helmet?
  1. Only riders on highways, not city streets
  2. Drivers and passengers under 18
  3. Only the motorcycle driver, never passengers
  4. All riders, with no exceptions

Answer: Drivers and passengers under 18

New Mexico law requires all motorcycle drivers and passengers under 18 years old to wear a helmet.

Handbook p. 40 ↗
What shape are most motorcycle mirrors, and what effect does this have?
  1. Convex; vehicles seem farther away
  2. Concave; vehicles seem closer
  3. Flat; distances look accurate
  4. Convex; vehicles seem closer

Answer: Convex; vehicles seem farther away

Most motorcycle mirrors are convex, providing a wider view but making vehicles seem farther away than they are.

Handbook p. 40 ↗
At night, why should a motorcyclist open up a three-second following distance?
  1. Headlights are dimmer, so speed drops
  2. Distances are harder to judge at night
  3. Motorcycle brakes work worse at night
  4. It is required only for group rides

Answer: Distances are harder to judge at night

Increase distance at night since distances are harder to judge than during the day.

Handbook p. 41 ↗
In a staggered group riding formation, where does the lead rider position?
  1. The left side of the lane
  2. The center of the lane
  3. The right side of the lane
  4. Directly behind the second rider

Answer: The left side of the lane

In staggered formation, the leader rides in the left side of the lane.

Handbook p. 41 ↗
In staggered formation, how far behind the leader does the second rider stay?
  1. Half a second, directly behind
  2. One second, on the right side of the lane
  3. Two seconds, on the left side of the lane
  4. Three seconds, in the center

Answer: One second, on the right side of the lane

The second rider stays one second behind the leader, in the right side of the lane.

Handbook p. 41 ↗
When passing while riding in a staggered formation, how should riders proceed?
  1. Only the lead rider is allowed to pass
  2. In pairs, matched by position
  3. One at a time, back to the left after
  4. All at once, side by side

Answer: One at a time, back to the left after

Riders in a staggered formation should pass one at a time, and the leader returns to the left position after passing.
