These tips will help you have a comfortable ride in various conditions.

1. Be aware of your physical condition.
You need good vision and good hearing, and you must be alert and responsive.
Never drive when:

1. You have been drinking alcohol.
2. You have taken any prescription or over-the-counter medicine that can cause drowsiness.
3. You are under the influence of any drug that may affect your performance or perception.
4. You are very tired.
5. You are emotionally upset — these can all cause you to become less alert and less responsive.
