What To Do
- Move as quickly and as safely out of the way as possible.
- Do not attempt to pursue the wrong-way driver. As soon as it is safe to do so, call 911 and report the driver.
- While driving, maintain a high visual horizon. Looking down the road increases your ability to see roadway hazards far ahead and safely get out of the way.
- Keep your headlights on at night. If a wrong-way driver sees headlights, they might realize they are going the wrong way.
