What is the safest speed to drive your car?
Explanation : You must obey the posted speed limit, or, if no limit is posted, drive no faster than 55 mph (88 km/h). the legal limit on an icy or foggy expressway might be 55 mph (88 km/h), but the safe speed to drive would be much lower.
Why does my car only go 30 mph?
It may be that the emission control system is clogged with oil. It may also be worth pulling the lambda probe in the exhaust. If this is fouled with oil, it may be that it’s getting an artificially rich fuel reading and is unable meter out the engines fuel demands properly.
Why does my car have reduced engine power?
Failing to do so can result in the vehicle entering Reduced Engine Power Mode. Some GM vehicles will enter Reduced Engine Power Mode when the engine begins to overheat due to cooling system issues. Some GM vehicles will enter Reduced Engine Power Mode when the engine begins to overheat due to cooling system issues.
What happens when you go over the speed limit?
Higher speeds mean that drivers have less time to identify and react to what is happening around them, and it takes longer for the vehicle to stop. It removes the drivers safety margin and turns near misses into crashes. Around two-thirds of crashes in which people are killed or injured occur on roads with a speed limit of 30 mph or less.
What happens if average speed is reduced by 1 mph?
If average speeds reduced by 1 mph, the accident rate would fall by approximately 5%2,3.

What happens if you reduce the speed of a car?
— Studies suggest that a 1 km/h decrease in travelling speed would lead to a 2–3% reduc- tion in road crashes. — Experience in many countries has shown that the introduction of speed limits will only have a short lived effect on reducing speeds unless accompanied by sustained, visible enforcement of these limits.
Why does my car not run at low speeds?
With sub-optimal power, the car will not be able to continue running when it is at low speeds. The same is true with a bad or dirty oxygen sensor. This sensor tells the computer if there is too much oxygen in the fuel air mixture or too little oxygen. This way, the computer will make the necessary adjustments in fuel delivery.
