What Are the 10 Main Causes of Accidents
The 10 main causes are distraction, speed, inexperience, impairment, fatigue, weather, signal violations, tailgating, and bad turns.
Why these ten keep showing up in every crash report
Almost every collision traces back to one of a few failures, attention, judgment, space, or control. Distraction breaks attention. Speed and tailgating remove the space needed to react. Inexperience and night driving strain judgment before it has fully formed. Impairment and fatigue weaken control over the vehicle itself. Weather and improper turns add conditions the driver has to read correctly and often doesn't.
For a new driver, several of these overlap in ways they don't for an experienced one. A teen hasn't logged enough hours behind the wheel to build the instinct that tells an adult driver when a gap is too small or a curve is coming up fast. That's not a character flaw, it's a timing problem. The skill that prevents these ten causes is built through repetition, and a sixteen or seventeen year old simply has less of it banked.
This is also why insurers price teen drivers the way they do. It isn't a judgment about your child specifically. It's that the statistics behind these ten causes are heaviest in the first years of driving, for every teen, everywhere. The rate reflects the category, not a prediction about your kid.
Where this varies is in which causes dominate locally. A state with long winters sees more weather-related crashes among new drivers. A state with high speed limits on rural roads sees more speed-related ones. Check what your state's driver safety office or insurer publishes about local teen crash data, because that can tell you which of the ten to focus your coaching on first.
Which of these ten should I worry about most for my own teen?
Distraction and inexperience together cause more teen crashes than the other eight combined, and they compound each other. An experienced driver can handle a moment of distraction because instinct covers the gap. A new driver often can't, because the instinct isn't built yet.
That makes phone use the single highest-leverage thing to address, not because the other causes don't matter, but because removing distraction gives your teen's developing judgment a fighting chance to catch the rest. Start there, then layer in night driving limits and passenger limits as they gain hours. Check whether your state has specific restrictions for new drivers, since many do.
Once you know which causes put your teen most at risk, compare quotes built around how you plan to manage it.
The ten causes, and what each one means for a new driver
- Distraction Phones, passengers, and dashboards pull attention at the worst moment. Set a no-phone rule in the car and consider an app that locks it while driving.
- Speeding Misjudging how fast is too fast for the road is common in new drivers. Practice on the actual roads they'll drive daily, not just open ones.
- Inexperience Reaction time and hazard recognition both take real hours to build. Log supervised miles across different conditions, not just easy ones.
- Impaired driving Alcohol and drugs impair judgment fastest in drivers who have the least practice compensating. Talk about this directly and keep the conversation ongoing, not a one-time warning.
- Fatigue and night driving Teens underestimate how much tiredness affects reaction time at night. Set a curfew for driving until confidence and skill are clearly established.
These ten causes aren't bad luck, they're skills your teen hasn't finished building yet.
Does adding my teen to my policy increase my rate even if they rarely drive?
Yes, in most cases, because insurers price based on who is eligible to drive the car, not how often they actually do. Being listed as an occasional driver can sometimes lower the adjustment compared to being the primary driver of a vehicle, but check with your insurer, since this varies and some states handle occasional drivers differently than others.
Will a fender bender in the first year raise rates more than a minor ticket?
Generally a crash with a claim affects rates more than a minor ticket, because insurers weigh the cost of an actual payout heavily. But this depends on the type of ticket and your insurer's specific rules, so ask directly what counts as a major versus minor incident on your policy before assuming either way.
Does defensive driving training actually lower what I pay for my teen?
Often yes, many insurers offer a reduction for completed driver training or defensive driving courses, though not all do and the course has to meet their specific requirements. Check with your insurer which programs qualify before enrolling, since an uncertified course may not count for anything on your policy.
