Because of its small size a motorcycle seems to be moving faster than it really is. When checking traffic to turn at an intersection, assume a motorcycle is closer than it looks.
Motorcyclists often adjust position within a lane to be seen more easily and to minimize the effects of wind, road debris, and passing vehicles. Understand that motorcyclists adjust lane position for a purpose, not to be reckless or show off.
Because of its small size, a motorcycle can easily be hidden by objects inside or outside of a car, such as door posts, mirrors, passengers, bushes, fences, bridges, blind spots, etc. Take an extra moment to thoroughly check traffic, whether you’re changing lanes or turning at intersections.
Mirrors are smaller on a motorcycle and are usually convex, thus giving a motorcycle a smaller image of you and making you seem farther back than you really are. Keep at least a three or four second space cushion when following a motorcyclist.
Stopping distance for motorcycles is nearly the same as for cars, but slippery pavement makes quick stopping difficult. Allow a motorcyclist more following distance because it can’t always stop “on a dime.”

To apply for a motorcycle permit, you must be at least 18 years of age, or you must hold a valid operator's license. Applicants for a motorcycle license permit who are under 18 years of age, however, must have a parent or legal guardian who is willing to assume the responsibility imposed by KRS 186.590 sign the application for a license. This is true even if the parent or guardian has already signed the application allowing the minor to drive a moped or automobile.
