Are you aware that it is a traffic offense to drive too slowly in Arizona? Older drivers or newcomers may find it difficult to drive at the accustomed speed on our highways. When a driver cannot keep up with the speed of the other drivers on the highway, he presents a danger to himself and others. Sometimes, this results in car accidents. According to A.R.S. § 28-704(A):
A person shall not drive a motor vehicle at such a slow speed as to impede or block the normal and reasonable movement of traffic (with stated exceptions).
If you are driving on a major highway, and cars are following close to your bumper, you may decide to ignore them if you are driving at the posted speed limit and allow them to go around you. If you are going under the posted speed limit; however, you ought to speed up.
If you are on a secondary road and you notice that more than one car is following close behind you, it is common courtesy to pull over at the first opportunity and allow the string of cars to pass you. In fact, according to A.R.S. § 28-704(C), it is a requirement of law:
If a person is driving a vehicle at a speed less than the normal flow of traffic at the particular time and place on a two-lane highway where passing is unsafe, and if five or more vehicles are formed in a line behind the vehicle, the person shall turn the vehicle off the roadway at the nearest place designated as a turnout by signs erected by the director or a local authority, or wherever sufficient area for a safe turnout exists, in order to permit the vehicles following to proceed.
Although Arizona Department of Transportation does not regularly post minimum speed limits, it is possible that it would do so if a stretch of road is known to be plagued by slow driving that causes accidents. Consequently, you should do your best to blend in with existing traffic without exceeding the speed limit. If driving at faster speeds makes you uncomfortable, research an alternate route to your destination. Secondary roads may take you longer to reach your destination, but arriving safely is more important.
