Borrowed Helmet for a 16-Year-Old Passenger
You are 18, have a motorcycle endorsement, and plan a 14-mile evening ride in July on a 250cc bike. Your 16-year-old cousin wants to ride as a passenger. You have a full-face DOT helmet, armored jacket, gloves, and over-the-ankle boots. Your cousin has a borrowed half helmet with a DOT sticker, but it is a size large and rocks when he shakes his head. The chin strap is frayed and can be pulled loose. He has no eye protection, and he plans to wear a hoodie, jeans, and running shoes. The route includes a 55 mph two-lane highway and a short stretch of gravel driveway. Your cousin says the helmet is 'better than nothing' and that Idaho only requires helmets for people under 18, so he is covered. He is 16.
1. Does the borrowed helmet satisfy Idaho's helmet requirement for this passenger? Explain.
Read the worked answer
No. Idaho requires motorcycle operators and passengers under 18 to wear a helmet, and your cousin is 16. The DOT sticker is necessary but not enough by itself: the helmet must fit and be properly fastened to do its job. This helmet is a size large, rocks when he shakes his head, and has a frayed chin strap that can be pulled loose. In a crash, a loose helmet can rotate or come off before it protects the head. The statement that 'Idaho only requires helmets for people under 18' actually confirms that he is covered by the law, not exempt from it. He should not ride until he has a properly fitting, undamaged, DOT-compliant helmet that stays in place when fastened.
2. What protection problems remain even if the helmet fit is fixed?
Read the worked answer
Even with a good helmet, the rest of the gear is inadequate for a 55 mph highway ride. A hoodie and jeans provide almost no abrasion resistance; at highway speed, a fall can grind through denim quickly. Running shoes offer little ankle support and can come off in a slide. No eye protection means wind, insects, and road debris can impair vision or cause eye injury, and a half helmet leaves the face exposed. The passenger also needs to understand how to sit, hold on, and lean with the rider. The right fix is a properly fitted helmet with eye protection, plus an armored jacket, gloves, long pants, and over-the-ankle boots, or a decision to leave the passenger home until the gear is available.
3. Your cousin argues that the ride is short and he will 'hold on tight.' What do you decide?

I would not take him on the highway with that gear. 'Short' and 'holding on tight' do not reduce the physics of a crash at 55 mph, and a passenger who is not properly equipped can also distract the rider. I would either borrow or buy a correctly sized helmet and proper gear before the ride, or leave him home. If we ride at all, it should be after the helmet fits and fastens securely, he has eye protection and real riding gear, and we have practiced mounting, stopping, and leaning at low speed in a lot. The legal minimum is not the same as adequate protection, and the rider is responsible for the passenger's safety.
