What is the safest speed to drive?

When there is no stated speed restriction on the interstate, 55 mph is the safest driving speed on a rural highway. However, a safe speed on residential roads is between 10 and 25 mph. The fastest speed to drive is the posted speed limit.


Is it safer to drive slow or fast?

Driving slower than the surrounding traffic is more likely to cause an accident than speeding, according to research. Driving too slowly can make other drivers around you constantly brake and speed up. It can be frustrating for other drivers, cause confusion and could lead to an accident.

At what speed do most accidents happen?

70 MPH is the average speed limit on most US highways. It is also the speed at which a fatal car accident becomes practically inevitable.


What is a good driving speed?

About 55 miles per hour is the optimum speed for most cars. Kick it up to 65 mph and you are 8 percent less efficient; at 80 mph you are 28 percent less efficient. Slowing down can also mean reducing your carbon footprint.

What speed should I drive to save gas?

While vehicles reach optimal fuel economy at different speeds, gas mileage usually decreases rapidly at speeds above 50 miles per hour (mph). For light-duty vehicles, for example, every 5 mph you drive over 50 mph is like paying $0.18 more per gallon of gas (based on the price of gas at $2.63 per gallon).


Understanding Appropriate Driving Speeds - Driving Tutorial



Do you save gas if you drive slower?

The short answer: Nope. The reason: The common understanding is that going faster burns more fuel and therefore, the slower you drive, the less fuel your car will use, but this actually isn't true. Most cars' peak fuel efficiency occurs somewhere between 50-60 miles per hour.

Can you survive a 30 mph crash?

The U.S. Department of Transportation (DOT) estimated that about 40 percent of people who get hit by a motor vehicle going 30 mph will die from their injuries. For comparison: About 5 percent would not survive getting struck by a motor vehicle traveling at 20 mph.

Why do people drive so fast?

Drivers often exceed the speed limit simply because they're not paying attention to their driving speed. Factors such as traffic flow, driving a powerful vehicle, and playing music were cited as contributors to speeding. Some motorists also blamed their speeding on being distracted by passengers.


Where do crashes happen the most?

The most common places that experience automobile accidents are rural areas, interstates, intersections, and parking lots. Additionally, most vehicle mishaps happen close to an accident victim's home.

Can driving too fast hurt your car?

When you drive your car too fast, you are putting a lot of stress on the engine. This can cause the engine to overheat and eventually fail, leading to expensive engine repairs or even replacing the engine entirely.

How slow is too slow driving?

On a road with one lane in each direction, going 10-mph is legal, but can impede the flow of traffic. If it's safe to do so, drive closer to the max speed limit. If you're driving so slow that a line of more than five cars has queued behind you, it's best to pull over to the shoulder and allow the drivers to pass you.


Why is 55 mph the most efficient speed?

So, why 55? Well, it has to do with wind resistance, actually. It turns out that when it comes to wind resistance, at 30 mph wind resistance is four times as great compared to when a car is going 30 mph.

What is the #1 cause of accidents?

1. Distracted Driving. Undoubtedly, distracted driving is the number one cause of car accidents. A distracted driver does not have their complete attention on the road, and they may be paying closer attention to a mobile device, passengers, or even a cheeseburger.

Which body part is hit first in a car crash?

For people riding on the struck side of the car, severe injuries are most commonly delivered to person's neck, followed by the head, chest, legs, and abdomen/pelvis. For car occupants riding on the non-struck side of the car, head injuries are most common, followed by chest injuries.

At what speed do airbags deploy?

Typically, a front airbag will deploy for unbelted occupants when the crash is the equivalent of an impact into a rigid wall at 10-12 mph. Most airbags will deploy at a higher threshold — about 16 mph — for belted occupants because the belts alone are likely to provide adequate protection up to these moderate speeds.

Which lane is safest on highway?

According to the National Highway Traffic Safety Administration's (NHTSA) Crashworthiness Data System, the safest lane seems to be the left lane with the fewest crashes.


Can you survive a 70mph crash?

In crash studies, when a car is in a collision at 300% of the forces it was designed to handle, the odds of survival drop to just 25%. Therefore, in a 70-mph head on collision with four occupants in your car, odds are that only one person in the car will survive the crash.

What wastes the most gas in a car?

Speeding shouldn't come as a surprise as one of the top ways to waste gas. When you speed, you force your car to operate at a higher level that requires more gas and the more you speed, the more gas you'll use. For the best MPG performance, our fleet fuel card company suggests driving at a speed of 55-60 mph.

Why not top off your gas tank?

Gas topping damages your car.

Overfilling the gas tank can cause liquid gas to enter the charcoal canister, or carbon filter, which is designed only for vapor. Gas in the system can affect your car's performance by causing it to run poorly, and damage the engine, he says.


What is the most fuel-efficient way to drive?

Drive conservatively. Avoid "jack rabbit" starts, rapid acceleration and hard braking, which can lower fuel economy by 15 to 30 percent at highway speeds and 10 to 40 percent in stop-and-go traffic. Shift gears efficiently. If your car has a manual transmission, upshift as soon as practical.
