How to prevent car accidents: 9 tips for teens and parents

Car accidents can happen in an instant, but most are preventable with the right habits and tools. Whether you’re a new driver or a seasoned commuter, it pays to stay alert and know how to reduce your risks on the road.

With weather, distractions, and other drivers in the mix, there’s a lot to keep track of. In this article, we break down how to prevent car accidents with practical tips, essential safety features, and guidance for teen drivers.

1. Avoid the top causes of car accidents

Most crashes boil down to a few common behaviors. According to the National Highway Traffic Safety Administration (NHTSA), here are the big ones to watch out for:

• Distracted driving, including texting, eating, and adjusting the GPS

• Speeding, especially in poor weather or heavy traffic

• Driving under the influence of alcohol, drugs, or even fatigue

• Tailgating and not leaving enough distance to stop

• Running red lights or stop signs

What you can do:

• Keep your phone out of reach or use Do Not Disturb mode.

• Leave 3 seconds of distance between you and the car in front of you. 

• Obey all traffic signs and lights, even on empty roads.

• Never drive tired. Swap drivers or pull over if needed.

• Model safe behavior for young or teen passengers.

2. Drive smart in all weather conditions

Poor weather is a major contributor to crashes. According to the Federal Highway Administration, weather is a factor in about 21% of all crashes. Here's how to prep:

In the rain:

• Turn on headlights, even in the daytime.

• Drive slower than the speed limit to avoid hydroplaning.

• Leave extra space for stopping.

In snow or ice:

• Use snow tires or chains when needed.

• Brake gently and early.

• Avoid cruise control.

• Keep emergency supplies in the car.

In fog:

• Use low-beam headlights.

• Slow down and open windows to hear nearby traffic.

• Use the right edge of the road as a visual guide.

3. Take advantage of safety features

Modern vehicles come with helpful tools that can significantly reduce the chance of an accident. If you're buying or upgrading a car, prioritize these features:

• Automatic emergency braking (AEB): Helps prevent rear-end collisions.

• Blind spot warning (BSW): Alerts you if a car is in your blind spot.

• Rear cross-traffic alert: Helps when backing out of tight spots.

• Lane departure warning or assist: Nudges you back into your lane.

• Adaptive cruise control: Maintains a safe distance from cars ahead.

These features give you extra reaction time, which is especially helpful for new or distracted drivers.

4. Teach and coach safe driving habits

Young drivers are more likely to crash due to inexperience. But with the right coaching, you can help build skills that stick.

Tips for teen driver safety:

• Create a driving contract with clear rules and consequences.

• Practice together in various conditions.

• Set a good example when you drive.

• Use an app or tool that provides real-time driving feedback.

5. Maintain your vehicle regularly

Regular maintenance can prevent mechanical issues that lead to accidents. Even small issues, like a worn wiper blade or low tire pressure, can turn into big safety risks.

What to check:

• Brake pads and fluid

• Tire pressure and tread depth

• Lights (headlights, brake lights, turn signals)

• Oil, coolant, and transmission fluid

• Wipers and windshield washer fluid

Add reminders to your calendar or use an app to help track what needs attention.

6. Stay well-rested and alert

Driving while tired can be just as dangerous as driving under the influence. According to the CDC, drowsy driving contributes to tens of thousands of crashes each year.

To stay alert:

• Get at least 7 hours of sleep before long trips.

• Take breaks every 2 hours or 100 miles.

• Avoid driving during your usual sleep hours.

• Share driving responsibilities on road trips when possible.

7. Eliminate distractions inside your car

Phones aren’t the distraction. Eating, adjusting the radio, or turning to talk to passengers can all take your eyes off the road.

Tips to reduce distractions:

• Set your GPS and music before you drive.

• Avoid eating while driving.

• Use voice controls or hands-free devices when needed.

• Encourage calm, quiet passengers, especially if you're driving with kids or teens.

8. Follow speed limits and adapt to road conditions

Speeding reduces your reaction time and increases the severity of crashes. It’s also one of the most common causes of accidents.

What helps:

• Follow posted limits. They’re set for a reason.

• Adjust your speed based on traffic and weather.

• Use cruise control wisely, and avoid using it in wet or icy conditions.

• Leave extra room when merging or passing.

9. Plan your route ahead of time

Last-minute lane changes or missed turns can cause sudden stops or swerves, which is a recipe for accidents.

Try this:

• Use a navigation app that updates in real time.

• Check traffic conditions before you leave.

• Leave early to avoid rushing.

• Familiarize yourself with tricky intersections or exits ahead of time.

It all adds up to safer roads

You can’t control every twist and turn, but the choices you make behind the wheel—and at home—matter. From setting ground rules with your teen to checking your tire pressure or just putting your phone away, every action helps create a safer ride for everyone.
