Illinois could soon join the majority of states by raising the speed limit on highways to 70 mph. A bill to do that awaits the governor's action and has passed with enough votes in the House and Senate to suggest it would survive a veto, if there is one. “The average speed that vehicles drive on the interstate is 72 to 74 mph across the country,” said the sponsor, State Rep. Jerry Costello II (D-Smithton).

“When you reach that 85th percentile, which is the safest free flow of traffic, that is an extremely important speed from a safety aspect. The disparity in speeds is what, many times, causes accidents.” “For every increase in 5 mph over the posted speed limit, it takes an 80,000-pound vehicle another 100 feet to stop,” said State Rep. Jim Sacia (R-Pecatonica), who added his business owns two trucks that size. SB 2356 has passed the House, 85-30, and goes to the governor.
