Last year 13 people were killed on Missouri roads over the Independence Day holiday. The Missouri Department of Transportation offers some tips for staying safe this weekend:

Buckle up - every trip, every time - safety belts save lives.

Don't drink and drive - impairment of any kind is dangerous. Designate a sober driver.

Don't speed - note the posted limits and adjust for weather and traffic conditions.

Pay attention and stay alert - dedicate your full attention to the roadway.

Obey traffic rules and signs - they are there to help you.

Plan your trip - determine your route before you leave.

Get plenty of rest before your trip - change drivers if you feel tired.

Be patient and courteous.
