You must always stop before crossing railroad tracks if flashing red lights are activated, a crossing gate is lowered, a stop sign is posted, a flagger signals you to stop, or a train is visible or so close to the crossing that it would be hazardous to continue driving. If you are unsure if a train is too close for you to safely cross the tracks, stop. Never race a train.

White lines are used to separate traffic moving in the same direction. Dashed lines indicate that drivers directly next to the line are permitted to pass when it is safe to do so.

Alcohol dulls the parts of your brain that control inhibition, judgment, and self-control. As a result, you may feel stimulated, lively, and a bit giddy or foolish after consuming alcohol. Alcohol also impairs your reaction time, coordination, and balance. Your vision and ability to judge distance suffers after alcohol consumption, making it difficult to react to your surroundings.

In many collisions with motorcycles, bicycles, and pedestrians, drivers reported that they were looking but still did not see the smaller vehicle or pedestrian. These can be more difficult to spot in traffic than passenger vehicles because they are smaller, may move faster, and have less noticeable lighting. To prevent collisions with these smaller and less protected road users, drivers should always be alert to the presence of motorcycles, bikes, and pedestrians.
