TRAFFIC RULES IN ILLINOIS & MISSOURI

If you're planning to attend the Enjoy Illinois 300 at Technology Raceway, your focus should be on the roar of engines and the one-of-a-kind race day atmosphere, not on unexpected fines or confusion behind the wheel. Since the track sits near the border of Illinois and Missouri, visitors often find themselves driving in both states during the weekend. That’s why it's useful to understand the basic traffic rules for each.

Driving in Illinois & Missouri

Like the rest of the United States, drivers in both Illinois and Missouri drive on the right-hand side of the road. If you're not used to this, pay extra attention at intersections, when making turns, or when exiting parking lots.

Speed Limits

• Residential areas: typically 25–30 mph (40–48 km/h)
• Highways: usually 55–65 mph (89–105 km/h)
• Interstates: up to 70 mph (113 km/h) in most cases

Always obey posted signs and adjust your speed based on weather or traffic conditions. Speed is monitored by radar, especially in Illinois, and fines for violations can be high.

Traffic lights and intersections

Obeying traffic signals is taken seriously. Many intersections in Illinois and Missouri are equipped with red light cameras. One common U.S. rule: You may usually turn right on red after a full stop, unless a sign says otherwise. Always yield to pedestrians and cross traffic before turning.

Alcohol and driving

Both Illinois and Missouri enforce strict DUI laws. The legal BAC limit is 0.08% for drivers over 21. For those under 21, any amount of alcohol is a violation. DUI checkpoints are sometimes in place on race weekends or holidays. If you plan to drink, use a designated driver, a taxi, or a rideshare.

Seat belt laws

Seat belts are required for all passengers, not just those in the front. Police in both states can pull you over solely for a seat belt violation, so double-check that everyone is buckled up before you drive off.

Right-of-way and pedestrian rules

Drivers must yield to pedestrians at crosswalks and in school zones. At intersections without traffic lights, the first vehicle to arrive has the right of way. If two vehicles arrive at the same time, the one on the right goes first. Be especially alert for pedestrians around the track and in nearby towns during race weekend.

If you're pulled over by the Police

If law enforcement signals you to stop, stay calm. Use your turn signal and pull over safely to the right-hand side of the road. Try to stop in a well-lit area, especially at night. Keep your hands visible and wait for instructions. Cooperating respectfully can make the situation quick and smooth.
