Traffic jams, road rage and speeding plague all the nation's highways, but some states have taken a tougher stance than others when it comes to bad drivers. 

With average highway speeds much higher than back when the national highway speed limit was 55, some states are cracking down on speeding and other traffic violations.

Safety concerns are not the only reason to slow down on the road: According to the U.S. Department of Energy, every 5 mph driven over 60 mph drives up fuel costs by 7 percent.

WallettHub looked at enforcement data for all 50 states and Washington, D.C., including speeding penalties, cost of insurance after tickets, use of automatic speed cameras, reckless driving fines and jail time for convictions, to find out which states had the toughest penalties against bad drivers.

These are the strictest states, in ascending order, based on the data:

8. (Tie) Washington

Speeding enforcement came in at No. 8. Reckless driving results in maximum fines for the first and second conviction.
