Introduction
Speeding is a significant factor in accidents involving commercial vehicles. As a CDL Class A truck
driver, adhering to speed limits is essential for safety, compliance, and avoiding violations.
State-Specific Truck Speed Limits
Arizona
- General truck speed limit: 65 mph on highways unless otherwise posted.
- Some rural areas may allow up to 75 mph, but always follow posted limits.
- Watch for speed changes near urban areas and construction zones.
Nevada - Truck speed limits vary between 65-70 mph on highways.
- Always pay attention to posted signs as limits can change.
- Be cautious on highways like I-15 and I-80, where enforcement is strict.
California - Statewide truck speed limit: 55 mph, even on interstates where cars can travel at 70 mph.
- Strict enforcement, particularly on major routes such as I-5, I-10, and I-15.
- Heavy penalties for violations, including fines and CDL points.
Dangers of Speeding in a Commercial Vehicle
- Increased Stopping Distance: A fully loaded truck can take over 500 feet to stop.
- Higher Risk of Rollovers: High speeds make turns and ramps dangerous.
- Mechanical Stress and Failures: Faster speeds increase wear on brakes and tires.
- Legal and Financial Consequences: Speeding violations can lead to CDL suspension.
How to Prevent Speeding
- Monitor Speed Limits: Use truck-specific GPS and pay attention to posted signs.
- Use Cruise Control Wisely: Helps maintain speed but avoid it in heavy traffic or steep grades.
- Plan Your Route: Avoid rushing by accounting for delays and high-enforcement areas.
- Adjust for Road Conditions: Slow down in bad weather and on steep grades.
- Understand Consequences: Protect your CDL by staying within legal speed limits.
Conclusion
Following posted speed limits isn’t just about avoiding tickets-it’s about protecting your CDL, your
job, and lives on the road. By maintaining a safe speed, you reduce your risk of accidents, costly
violations, and mechanical failures.
Safe travels!
