Mount Pleasant police say two drivers, both of Racine, are facing potentially hefty fines after racing up Highway 31 early Sunday morning at speeds that exceeded 100 miles per hour.

Officers on patrol at 6:53 a.m. Sunday were southbound on Highway 31 when they observed two vehicles racing north toward Durand Avenue. The drivers were clocked at 109 mph in a 55 mph zone so officers activated their lights and sirens in pursuit.

The driver, 49, of a Toyota Avalon slowed down and pulled over. They were cited for racing on a highway, speeding and operating without insurance.

Police caught up to the other driver, 38, after they turned east on Durand Avenue. They were behind the wheel of a Cadillac Deville and issued citations for racing on a highway and speeding.

Both drivers were released. No one was injured as a result of their racing.
