The Iowa House of Representatives has passed a bill that would raise the speed limit on interstate highways to 70 mph for cars, but keep it at 65 mph for trucks.

The Owner Operator Independent Drivers Assn. reports that HF268, sponsored by the House Transportation Committee, passed all House committees with amendments on Feb. 13.
The amended version raises fines from $10 to $100 for speeds not more than 10 mph over the limit in a speed zone; from $40 to $200 for speeds greater than 10, but not more than 20 mph in excess of the limit; and from $60 to $200, plus $25 for each mph exceeding 20 mph over the limit.
Under the provisions of this bill, all revenue from speeding tickets will go to local law enforcement for the purchase of new police vehicles, reports OOIDA.
While earlier proposals included divided state highways, this measure would affect only interstate highways. Because of this, and the fact that it does not raise the speed limit for trucks grossing more than 10,000 pounds, the bill is expected to have a greater chance of passing than previous attempts to raise the speed limit in the state.
OOIDA is urging Iowa members who opposed the split speed limits to talk to their state senators.
