Drivers who encounter this checkpoint are asked to have their driver’s license and registration available for troopers.

The Indiana State Police Bremen Post offers the following tips:

• Use a designated driver

• Don’t get behind the wheel if you have been drinking. Call a taxi, ride sharing service, friend or family member that has not been drinking.

• If you are hosting a party, offer non-alcoholic drinks as an option

• Don’t let friends drive drunk. Offer to get them a ride or spend the night.

• If you see a possibly impaired driver, call 911 and be prepared to give a location, direction of travel, and vehicle description.
