St. Louis Red Light and Stop Sign Laws Refresher


Traffic lights and signals are there to protect drivers and pedestrians. When they are ignored the results can be serious.

Though many St. Louis residents think they understand intersections perfectly, many of them would fail if you gave them a test on the subject. The reason is that there are a few confusing intricacies that many drivers don’t fully understand.

Intersection Car Accident

When to Stop

Four traffic features require you to stop: Stop signs, red lights, flashing red lights, and traffic lights that are off. When doing so, make sure you come to a complete stop before starting again. Just slowing down to a low speed and then starting up again is insufficient. While stop signs and red lights are straightforward, many drivers do not know how to act when a stoplight flashes red or turns off. In these situations, you treat the intersection as if it were a four-way stop sign.

Right on Red

Though this law varies from state to state, Missouri allows drivers to turn right on red lights. When you do this, make sure that no other cars are coming down the road. If they are, wait for them to pass because they have the right of way. The one exception to the right on red rule is a sign indicating that you cannot turn. If there is, follow that sign over the general guideline.

Left on Red

Some states allow this kind of turn, but Missouri is not one. If you are turning left at an intersection, you must wait until your light is green before entering.

Yellow Lights

When you are heading towards an intersection and see a yellow light, that serves as a warning of the red light coming soon. The law indicates that you are allowed to enter the intersection in these situations as long as the light is still yellow. However, one thing to note is that last-second entries are often both unsafe and misinterpreted by police officers. It would help if you always leaned towards stopping over driving through a yellow light for these reasons.

Red Light Cameras

As you drive through St. Louis, you may come to an intersection with a red light camera. Not only will you see the camera, but there will also be a sign that says something like “photo enforced.” Though these devices and signs may still be up, the cameras themselves may not be functional. This is because Missouri supreme court deemed them unconstitutional. After all, they cannot confirm the driver’s identity solely based on the vehicle they are driving.

No matter who you are, brushing up on traffic laws is always an intelligent decision. When you do, you increase your odds of staying safe. Unfortunately, crashes are sometimes inevitable. If you suffer a collision, you can always call a St. Louis car accident lawyer for assistance.

Traffic lights and signals protect drivers, pedestrians, and bicyclists. When these signals are ignored, the results can be catastrophic. Any driver that runs a red light and causes an accident should be held responsible for their actions.
