FAQ: Driving in Denver
Do I need a car in Denver?
For the city itself, the RTD light rail and bus system is decent. For mountain day trips to ski resorts, Rocky Mountain National Park, or mountain towns, a car is essential. Consider AWD/4WD if visiting in winter.
What is the traction law on I-70?
Colorado's traction law (Code 15) requires adequate tires (all-weather M+S rated or snow tires) or chains on I-70 mountain corridor. Code 16 requires actual chains or an AWD/4WD vehicle. It's enforced in winter and violators face $130+ fines and delays.
How bad is ski traffic?
I-70 westbound is jammed Friday afternoons and Saturday mornings. Eastbound is brutal Sunday afternoons. A 90-minute drive to ski areas can take 4+ hours. Leave very early (before 7 AM) or very late to avoid the worst of it.
Does altitude affect driving?
Yes. At 5,280 feet (Denver) to 11,000+ feet (mountain passes), engines lose power, braking distances increase, and overheating is more likely. Drivers may feel fatigue and slower reaction times from altitude. Stay hydrated and take breaks.
