Michigan Gov. Rick Snyder (R) has signed new legislation that could eventually increase speed limits on certain roadways and also includes an increase from 60 to 65 mph for commercial trucks.

The bills, HBs 4423-2227, will allow the speed limit to be raised to 75 mph on 600 miles of freeways and up to 65 mph on at least 900 miles of non-freeway “M” roads. The bills also increase the maximum speed limit for trucks from 60 mph to 65 mph.

However, the speed limit increases will take effect only after the state conducts studies to ensure safety is not affected.

The increases will be approved if safety and engineering studies show that the 85th percentile of speeds currently driven on those roads allow for it. The bill will also adjust measures used by insurers to determine eligibility for auto insurance.

“Ensuring that all Michiganders are safe while operating vehicles on our state’s roadways is critically important, and these bills allow for appropriately increased speed limits on certain roadways after safety studies are conducted,” said Snyder.

    Truck speed limits do increase to 65 on most rural highways and freeways. Michigan is one of only 7 states that still has the counter-productive split limits for trucks. A few years ago a good bill to end the split limits was killed by AAA in a Senate Transportation Committee hearing. AAA threatened an elective Jihad against any Senator who voted for over 60 for trucks. This was despite one of the best research studies showing NO safety value for split truck limits came from the AAA Foundation for Traffic Safety. Fifty years ago AAA was the friend of the motorist, today they are an enemy.

    I Mam very happy to see the GOVERNOR OF Michigan take the bull buy the horn and raise the speed limit for trucks . The trucking industry always gets the blame for all freeway accidents and the four wheeler is always the good guy. Stand up for whats right not what some one tells you whats right. By the way I have 50 years in the Trucking Industry. Thanks for listening
