Speed limits on Florida highways could be raised to 75 mph under a bill passed by the state Senate.

The Senate voted 27-11 Thursday to pass the bill, despite concerns by some that it would make roads more dangerous.

The measure would allow the Florida Department of Transportation to raise the speed limit on interstate and limited-access highways from 70 to 75 mph, from 65 to 70 mph on rural, four-lane divided highways and up to 65 mph on other roads.

It does not automatically raise the speed limits.
