Most Dangerous Daily Traffic Times in St. Louis

According to the Missouri Department of Transportation, the worst traffic times are between 6-8:00 am when commuters drive to work. Between 5-6:00 pm, many drivers are out on the roads heading home in the early evening hours. But this period can be even more dangerous because alcohol consumption and driving often go hand-in-hand at night. Of crashes that occurred between 3-9:00 pm, one out of every three was fatal.

How Heavier Traffic Contributes to More Car Accidents

Many things cause traffic accidents, but it is clear that heavy traffic directly impacts the number of car crashes.

Driver Fatigue:

After focusing on the road for a long period or when driving while drowsy, people operating a motor vehicle may experience driver fatigue. Driving while fatigued can lead to failures in judgment and slower reaction times that result in rear-end collisions.

Not only does it increase the risk of crashes, but tired drivers are also more likely to run traffic signals and fail to yield the right-of-way at intersections. In 2017, driver fatigue resulted in 91,000 police-reported crashes involving drowsy drivers, 50,000 injuries, and almost 800 deaths across the U.S.


Speed is dangerous even if the road conditions are optimal. Driving above the posted speed limit in bad weather or during peak traffic hours further increases your risk of an accident and injury.

Besides increasing the risk of a collision, there are legal repercussions to speeding in Missouri. Driving anywhere from 5-20 MPH over the speed limit is considered a Class C misdemeanor, while exceeding 20 MPH over the posted limit is a Class B misdemeanor. These infractions can result in fines and even potential jail time.


Rubbernecking occurs when a driver consciously decides to take their eyes off the road to stare at something else. This could be due to another accident grabbing their attention or simply getting too caught up in new surroundings. Regardless of where you are or the weather conditions, it’s critical to remain focused on the road at all times when you’re in the driver’s seat.

Rear-End Collisions:

The National Highway Transportation Safety Administration estimates that 29% of all car accidents involve rear-end collisions. Rear-end collisions occur when one car is hit by another from behind. If a rear-end collision occurs on a highway at immense speed, it can sometimes result in the vehicle hit from behind rolling over, or being pushed off the road.

The type of injury victims can experience in these types of crashes depends on the car they collided with, their speed, and the weather conditions. These collisions could also occur because of distracted driving, inclement weather, or driving under the influence of alcohol or drugs.
