Iowa motorcycle Rider fitness and responsibility mix

A rider believes a prescription medicine cannot interfere with motorcycle operation because it was legally prescribed. What is correct?

Correct answer: Prescription and over-the-counter medicines can affect riding ability.

Legal availability does not establish fitness to ride. Medicines can impair the mental and physical processes needed for riding, and combining drugs with alcohol can increase the danger. Do not ride while impaired.

A rider says a small amount of alcohol improves confidence and therefore makes riding safer. What is the correct assessment?

Correct answer: Alcohol can reduce judgment and riding skill even when the rider feels confident.

Feeling confident is not a measure of unimpaired ability. Alcohol can interfere with judgment, reactions and the coordination needed to control a motorcycle. Choose a sober ride.

In its fatigue section, what minimum break frequency does the Iowa-linked motorcycle manual recommend for a long ride?

Correct answer: Stop and get off the motorcycle at least every two hours, and sooner if tired.

The fatigue section recommends stopping and getting off the motorcycle at least every two hours, and sooner if tired. Do not treat an interval as permission to continue while tired; rest and adjust the trip to remain alert.

Cold rain has made your hands numb and your clothing soaked. Why is continuing without addressing it unsafe?

Correct answer: Cold and wet exposure can impair control and increase fatigue.

Clothing must help keep the rider warm and dry as well as protected. Stop safely and address the exposure instead of riding with reduced feeling and control.
