State police say the driver should have heeded their warning to stay off the roads.

Louisiana State Police arrested a man in East Baton Rouge Parish after he rolled his vehicle off the road, leading to the discovery of 40 grams of cocaine in his vehicle.

The driver, 24-year-old Miguel Garcia-Aguilar, was suspected of being impaired, state police said.

Troopers arrested him on suspicion of DWI, posession of cocaine, reckless operation of a vehicle and driving under a suspended license.

State police said this is the second crash they have worked Saturday where impairment is suspected to have played a part in the crash.

They are urging all drivers to stay off the road until Tropical Storm Barry passes.
