According to AAA Texas, today is one of the heaviest travel days of the year as many Texans are returning home from Thanksgiving with their families.
DPS issued the following travel tips before the holiday:
Don't drink and drive. Designate a driver or take a cab.
Eliminate distractions, and don't text while driving.
Buckle up everyone in the vehicle — it's the law.
Slow down — especially in bad weather, construction areas and heavy traffic.
Slow down or move over for tow trucks and police, fire and EMS vehicles stopped on the side of the road with emergency lights activated — it's the law.
Don't drive fatigued.
Drive defensively, as holiday travel may present additional challenges.
Make sure your vehicle is properly maintained before your trip begins.
