Since bicyclists are granted all the rights and responsibilities as drivers of vehicles by §28-812, are cyclists required to have a driver’s licence? §28-3151 sets forth the conditions requiring a license: “a person shall not drive a motor vehicle … on a highway without a valid driver license”. But that rule appears in Chapter 8.
The rules which apply to bicyclists are restricted to those in Chapters 3, 4 and 5 as set forth in the applicability statute, and since 28-3151 resides in Chapter 8, it does not apply to bicyclists.
Nor would it apply regardless of which chapter it appeared in, since it specifically only applies to drivers of MOTOR vehicles. (see bicycles-are-not-motor-vehicles-and-why-it-matters for some further discussion)
