On Friday, January 1, 2010 a new law goes into effect in Ohio requiring that you turn on your lights when your wipers are on in rain, snow or fog. Failure to do so could result in a ticket and a $100 fine. A new state of Ohio law, which took effect this year, included the mandatory lights-on provision, but it allowed law enforcement to issue only warnings for six months. On Friday, the 1st of January 2010, the warnings will be replaced by tickets. The law requires drivers to turn on their headlights anytime the windshield wipers of the vehicle are in use because of precipitation.
To be safe, turn on your lights anytime there is precipitation of any sort of the windshield.
The violation is a secondary offense meaning a motorists cannot be stopped or cited only for failing to turn on their lights, but it can be tacked on to another violation such as a speeding violation in the new year.
There are two other motor vehicle laws included. One requires drivers to change lanes or slow down when there is a tow truck along the side of the road. Failure will be a third-degree misdemeanor with up to $300 fine plus court costs. The second change is to increase the speed limit for trucks from 55 mph to 65 mph on most Ohio interstates.
