If I am stopped by a police officer for speeding or other violation and I do not have my license with me, how long do I have to produce the license?

The operator must always have his/her license on his/her person or in some easily accessible place while driving a vehicle and must produce same upon the request of a police officer, M.G.L. Chap. 90, Sec. 11. You cannot go home and get your license and bring it to the officer. It is a civil infraction for not producing your license when asked to do so by an officer. This would also apply to a vehicle registration.
