Have you ever wondered why your truck stops at 100 mph? It’s not due to a lack of power. It’s a safety feature that protects the tires from the centrifugal force exerted at high speeds. This force can cause the treads to separate from the tire, leading to a blowout. Trucks have a governor that limits their speed to 100 mph to prevent this. Obeying the speed limit is essential for your safety and your tires’ longevity.

Why Pickup Trucks Have Speed Limiters
In the United States, pickup trucks are subject to the same federal regulations as passenger vehicles. One of these regulations limits the maximum speed a car can travel. Pickup trucks are classified as light-duty trucks, and their maximum speed limit is 55 miles per hour. The speed limit for trucks was reduced to 55 in 1987 to improve fuel economy. While some states have raised the speed limit for trucks on certain highways, the 55-mile-per-hour limit remains in effect.
How Do You Turn off the Speed Limiter on a Chevy Silverado?
If you want to increase your Chevy Silverado’s top speed, you may wonder how to turn off the speed limiter. The speed limiter is a feature that limits the truck’s top speed to help preserve the engine and transmission. However, if you want to experience the full potential of your Silverado, you can easily disable the speed limiter. Here’s how:
Procedure:
- Locate the silver box on the driver’s side of the engine bay, which is the Engine Control Unit (ECU).
- Remove the ECU’s cover using a screwdriver.
- Inside the ECU, you’ll see a row of black switches. Locate the button labeled “SPD LIMIT.”
- Flip the switch to the off position.
- Replace the cover on the ECU and start your truck’s engine. You should now have full access to your Silverado’s top speed!
It is essential to be extra cautious when driving at high speeds. Remember always to obey the speed limit and drive safely!
Why Is My Car Limiting My Speed?
Speed limiters are devices installed in vehicles to prevent them from exceeding a certain speed. While they are most commonly found in large trucks and buses, many passenger cars now come equipped with them. There are several reasons why your vehicle might need more speed. One possibility is that the limiter has been activated due to safety concerns. For example, the limiter may kick in to help prevent you from losing control when approaching an icy patch of road. Another possibility is that your car’s engine is not powerful enough to sustain high speeds for long periods. In this case, the speed limiter may protect your engine from damage. Whatever the reason, it is essential to be aware of your car’s speed limit and obey it for both your safety and the longevity of your vehicle.
What Cars Can Go 100 mph?
Several factors come into play for cars that can reach high speeds, including engine power, weight, and aerodynamics. Here are a few vehicles capable of reaching 100 mph or more:
- Porsche 911 Turbo S: Twin-turbocharged engine that produces up to 580 horsepower, with an aerodynamic body style that enables it to accelerate from 0 to 60 mph in just 2.8 seconds and reach a top speed of 205 mph.
- Audi R8 V10 plus: Naturally aspirated V10 engine with 610 horsepower, an aerodynamic body, and the ability to accelerate from 0 to 60 mph in just 3.2 seconds, with a top speed of 205 mph.
- Lamborghini Aventador S: V12 engine with 750 horsepower, an aerodynamic body, and the ability to accelerate from 0 to 60 mph in just seconds, with a top speed of 217 mph.
Conclusion
If your truck suddenly comes to a halt at 100mph, it does not necessarily indicate a mechanical issue. Instead, federal regulations have set the maximum speed for trucks at 55mph since 1987 to promote fuel economy. Although some states have raised the speed limit on select highways, the 55mph restriction remains in effect for most areas. Therefore, the next time you find yourself trailing a lumbering truck on the road, remember that their slow pace is mandated by law for a valid reason.
