You must make a quick straight-line stop on a conventional two-wheel motorcycle with good traction. Which brake input is appropriate?
Correct answer: Use both brakes; increase front-brake pressure progressively while controlling rear-brake pressure.
Use coordinated braking rather than relying on only one brake. Weight transfers forward during a stop, so avoid locking the rear wheel with excessive pressure. Learn the system on your motorcycle and practice with qualified instruction.

On a motorcycle without ABS, you accidentally lock the front wheel while stopping. What does the Iowa-linked motorcycle manual advise?
Correct answer: Release the front brake immediately, then reapply smoothly with less pressure.
Restoring front-wheel rotation allows steering control to return. This question is about an actual wheel lock on a non-ABS motorcycle, not a direction to pump functioning ABS brakes.

You need to stop in a curve, but straightening immediately would take you into another lane. What is the important adjustment?
Correct answer: Brake carefully while reducing lean, then increase pressure as the motorcycle becomes upright.
Do not leave your safe path merely to straighten. When an immediate upright stop is not possible, controlled braking and decreasing lean let more traction become available for stopping. Practical training is essential.

You must avoid debris by both reducing speed and making a quick swerve. How should those actions be coordinated?
Correct answer: Brake before or after the swerve, not during it.
A sudden direction change uses tire grip. Separating the braking and swerving phases avoids asking the tires to do both demanding jobs simultaneously.

A bend tightens beyond the part you can initially see. What should guide your approach?
Correct answer: Allow for changing curvature within your skill and the speed limit.
Curves may tighten, widen or lead directly into another bend. A cautious entry preserves options within your lane; an early glimpse does not establish the entire curve’s shape.

You cannot safely go around a small obstacle in your lane. Before crossing it on a two-wheel motorcycle, which preparation is appropriate?
Correct answer: Reduce speed first, keep the motorcycle upright and approach close to a right angle.
When a small obstacle cannot safely be avoided, prepare before contact and keep the motorcycle straight. This differs from swerving across traffic to force a right-angle railroad crossing.

Your motorcycle has just rolled over debris with a noticeable impact. What should you do before continuing the trip?
Correct answer: Pull over safely and inspect the tires and rims for damage.
An impact can damage a tire or wheel even if the motorcycle keeps moving. Stop out of traffic and check the affected parts before continuing.

Light rain has just begun after a dry spell. Why should you be especially cautious?
Correct answer: Water can mix with accumulated surface oil and reduce traction.
Early rain can create a slippery mixture before oil is washed away. Reduce speed, increase space and select the better-grip part of the lane as conditions permit.

You are approaching a wet painted marking and a metal cover in a bend. What is the safer plan?
Correct answer: Slow beforehand and use smooth controls across the slippery area.
Wet paint and metal can offer less grip. Plan early and avoid sudden braking, shifting or steering where traction is reduced.

On wet pavement, should a rider simply stop using the front brake?
Correct answer: No; use both brakes carefully with gradual pressure.
The front brake remains useful on a slippery surface, but abrupt pressure can cause a lock. Reduce speed before hazards and keep inputs gentle and controlled.

Tracks cross your lane at an angle. Turning to hit them at exactly 90 degrees would put you into another traffic lane. What is generally safer?
Correct answer: Continue straight within your lane rather than swerving into other traffic.
For tracks crossing your course, the Iowa-linked motorcycle manual generally favors staying straight in your lane. Do not create a collision risk merely to achieve a right-angle crossing.

A pavement seam runs nearly parallel to your path and you need to cross it where there is safe space. What angle does the Iowa-linked motorcycle manual recommend?
Correct answer: At least 45 degrees rather than edging across at a shallow angle.
A shallow approach can catch a tire and upset the motorcycle. Arrange enough safe room to cross at a sufficient angle without moving into occupied traffic space.
