State police are warning the public to be extra cautious when hitting the roads this Thanksgiving holiday.

Officials say speeding, following cars too closely and cellphone use can be blamed for the chaos of holiday travel. They say they see an increase in violations around this time of year.

Police say drivers can become impatient and forget how important it is to drive safely.

Troopers say they can instantly spot distracted, drunken or aggressive drivers on the road.

State police say that sometimes it's the things that aren't illegal that will get drivers into trouble, like checking GPS devices more often than necessary, pulling over on the highway rather than getting off an exit for non-emergencies and constantly changing lanes.

Troopers say the increased patrols will be present around the clock until Sunday evening.
