INDIANAPOLIS (AP): State police say troopers issued more than 100 tickets to drivers in the year since a law took effect requiring drivers to move over from the left lanes of highways in favor of faster vehicles.

The law allows police to issue tickets to left-lane drivers who don’t budge when they should reasonably know another vehicle is overtaking them. State police report troopers wrote at least 1,535 warnings and 109 tickets under the law since last July.

State police Capt. David Bursten tells WISH-TV the intent isn’t to penalize drivers for not yielding to others going 95 mph, but to discourage inconsiderate drivers who think they own the left lane and help avoid traffic backups.

The mandate does not apply during traffic congestion or bad weather.
