TRAFFIC RULES IN ILLINOIS

Heading to the NASCAR Cup Series race means dealing with busy roads around the Speedway, so knowing a few basic local driving rules will help keep your trip smooth and predictable. Illinois traffic laws are similar to those in most U.S. states, but there are some points worth keeping in mind.

Driving in Illinois

Traffic in Illinois moves on the right-hand side of the road. Visitors from left-hand-drive countries may need a moment to adjust, especially when turning at junctions or merging onto highways near the circuit.

Speed limits

Speed limits change depending on the location:

• Residential areas usually range from 25–30 mph (40–48 km/h).
• State routes typically run between 55–65 mph (89–105 km/h).
• Rural interstate highways may allow up to 75 mph (121 km/h).

Always follow posted signs, as limits can drop quickly near exits and junctions. Illinois police frequently use radar and cameras, and penalties for speeding can be significant.

Traffic lights and intersections

Red-light cameras are common in busy areas. A right turn on red is allowed after a complete stop unless signs indicate otherwise. Drivers must yield to pedestrians, and it’s best not to enter an intersection on a yellow if stopping safely is possible.

Alcohol and driving

Illinois enforces strict rules on impaired driving. The legal blood alcohol limit is 0.08% for drivers aged 21 and over, while underage drivers must have zero alcohol in their system. During major events such as the NASCAR weekend, authorities may set up DUI checkpoints near the Speedway. If alcohol is part of your plans, arrange a designated driver or use a taxi or rideshare.

Seat belt rules

Seat belts are required for everyone in the vehicle. Illinois is a primary enforcement state, meaning officers can stop you solely for not wearing one. Ensure all passengers are buckled before setting off.

Right-of-way and pedestrians

Drivers must stop for pedestrians at crosswalks and unsignaled intersections. The first vehicle to reach a stop sign goes first; if two vehicles arrive at the same time, the driver on the right proceeds. Expect increased pedestrian movement around Chicagoland Speedway before and after the race, so reduce speed and stay attentive.

If you’re stopped by the police

If an officer signals you to pull over, do so calmly and safely on the right-hand shoulder. At night, try to stop in a well-lit location. Keep your hands visible on the steering wheel, follow instructions, and remain respectful throughout the encounter.
