How to choose a safe speed to drive your car
Step 1: Consider the posted speed limit
Each state’s legislature establishes a set of statutory speed limits for specific types of roads. The posted speed limit (or regulatory speed limit) is the limit that’s enforceable by law and the one you’ll see on the speed limit sign. This could be the same as the statutory limit or it could be a limit established by a city, county, or state transportation agency. 2 Both statutory and posted limits vary between states, but often fall within a few miles per hour above or below those listed in the table below:
| Example of statutory speed limit |
---|
Residential, school district, and other pedestrian-heavy roadways | |
Rural highways with regular entry and exit points, driveways, etc. | |
Interstate highways with access limited to designated on and off ramps | |
“Special conditions” speed limits, such as school zones, work zones, or areas equipped with changeable message signs (CMS) to increase or decrease speed limits based on traffic volume | |
Step 2: Consider the road conditions
Traveling an interstate at 70 mph on a clear summer afternoon is well within the bounds of safety. But traveling the same road at that speed when it’s covered in ice or snow, or even wet with rain, is dangerous—slippery roads always require you to slow down and increase your following distance.
Step 3: Consider your visibility
Of course you should slow down during foggy conditions or when driving in heavy rain or snow, but many drivers don’t consider the need to slow down at night. Even the best set of headlights only allows for a fraction of the visibility you have during the day.
Step 4: Consider potential hazards
Some hazards are taken into consideration for you when speed limits are being set, but others—like animals, construction, or a routine traffic stop on the side of the road—can pop up at any moment.
As a safe driver, you should always be on the lookout for the unknown and unexpected, and be ready to slow your speed accordingly.
Penalties for driving at an unsafe speed
Driving at an unsafe speed carries inherent risks, but it can also lead to serious legal repercussions if you’re caught. Some of the most common penalties exceeding the maximum speed limit include:
Speeding tickets: Depending on where you’re ticketed, a speeding infraction may be classed as a minor offense or a misdemeanor. This means you could face not only fines and fees, but also potential jail time, license suspension or revocation, and higher insurance rates than when you had a clean driving record
. Reckless or careless driving charges: Most states have a provision under which speeding can be classified as a more serious offense, usually a higher-grade misdemeanor. This means higher fines and fees, more jail time, and a greater likelihood that you’ll lose your driving privileges.
SR-22 requirements: If your speeding ticket or reckless driving charge results in a license suspension or revocation, most states require SR-22 filings
to get your driving privileges reinstated. Since an SR-22 requirement signals to insurers you’ve engaged in seriously risky driving behaviors, you can expect much higher premiums
going forward.
FAQs
What is the safest speed to drive?
The safest speed to drive depends on the posted speed limit and the current weather and driving conditions. The posted limit will be the safest speed unless you also have to contend with increased traffic volume, decreased visibility, wet or icy roads, or other adverse conditions.
Is it safe to drive your car 100 mph?
No. Unless you’re a professional driver on a closed course, driving a car at 100 mph is never safe—and it’s not safe for professionals on closed courses either. It’s just safer than it is for an amateur driver.
What is a safe speed to turn a corner?
The safest speed at which to take a corner depends on the corner, your car, the posted limit, and the driving conditions. That said, taking a corner at around 15 mph or less will usually be safe. 3 Why should you drive slower in the rain?
You should drive slower in the rain because of decreased visibility and the dangers associated with wet roads. Since you won’t be able to see as well, you need to give yourself added time to react. Plus, the wet roads will make it more difficult to stop and could lead to hydroplaning.
How fast do you have to go to get a speeding ticket?
Technically, traveling even one mile per hour over the speed limit could get you a ticket. It’s always best to stick to the posted limit.
Is it safer to drive fast or slow?
You have more time to react when driving slowly, but if you’re in an area where most motorists are driving at a higher rate of speed, you can impede traffic flow and it can actually be more dangerous to drive slowly.
In short, it’s not necessarily safer to drive slowly—it’s safer to drive at the rate of speed most appropriate for the conditions in which you’re currently traveling. That means taking into consideration speed, road conditions, weather conditions, other drivers’ speeds, and other factors that may impact safety.
Can you survive a 70 mph car crash?
Yes, it is possible to survive a crash at 70 mph. That said, the likelihood of injury or death increases as the speed of travel increases—even if you’re wearing a seat belt.
What speed kills in a car crash?
Technically, any speed can kill in a car crash. That said, higher rates of speed carry a higher potential for injury and death.
Are slower speed limits safer?
Technically yes. Slower speeds provide more reaction time, making it easier to avoid a crash. This also increases pedestrian safety as the danger of injury and death increases
exponentially with each additional mile per hour a vehicle travels. 4 Do speed limits actually save lives?
Yes. Especially when it comes to crashes involving pedestrians, speed limits save lives.
