(KMOV.com) -- Illinois lawmakers took a step in approving a plan to raise the speed limit on state interstates, but not everyone supports the measure.
The measure would raise the speed limit to 70 miles per hour on Illinois interstates and toll ways. The current top speed on Illinois interstates is 65 mph. Four-lane divided state highways would not be affected by the bill.
Proponents said the change would add Illinois to the list of more than 30 states already allowing drivers to go 70 to 75 miles per hour.
State Senator Jim Oberweis of the Oberweis Dairy franchise sponsored the bill. He calls it business friendly and said it would no doubt save time for his delivery drivers as well as those from other companies.
IDOT and Illinois State Police are against the measure because of safety concerns.
The bill would allow Madison and St. Clair counties in the Metro-East to opt out of the high speed limit if passed.
The bill must still go through the Illinois House before heading to Governor Pat Quinn's office.
If passed, the new speed limit would take effect January 1, 2014.
