Drunk Driving Involved in 24.3% of Fatal Accidents

Texas recorded 10,125 fatal accidents between 2018 and 2020, with 2,456 involving drunk driving. Driving under the influence is the second-leading contributing factor in fatal car accidents in Texas.

The dangers associated with alcohol-impaired driving are obvious. Apart from potentially injuring yourself, you may also injure those around you or cause property damage. Even a little bit of alcohol poses a danger to you and others. Texas' laws deem a blood alcohol concentration (BAC) of 0.8% as illegal, but even a BAC of 0.02% can make driving difficult.

Even when no accident occurs, drunk driving has serious consequences. It is possible to lose your driving privileges, have your license suspended and even go to jail for such an offense. On top of this, a DUI conviction can make finding affordable car insurance in Texas challenging, as getting Texas SR-22 insurance may be required and can result in substantial premium increases.

Speeding Is a Factor in 31.3% of Fatal Crashes

Speeding is the highest contributing factor in fatal crashes in Texas. Between 2018 and 2020, speeding was linked to 3,168 fatal accidents — or 31.3% of all fatal accidents within the state and time period.

When you drive at high speeds, you put yourself and others at risk. Whether you’re driving through the suburbs or racing along a highway, navigating the roads at high speeds can make it difficult to stop quickly when necessary. This added challenge can cause you to swerve or fail to stop entirely, increasing your risk of injury and property damage — which can put a dent in your finances and a mark on your driving history.

Distracted Driving Contributed to 9.9% of Fatal Accidents

Distracted driving, where you are unable to pay full attention behind the wheel, was linked to 9.9% of fatal accidents in Texas, or 1,001 accidents out of 10,125. On a national level, the Lone Star State ranks as the 13th worst state for distracted driving but is still better than 25% of other states.

October Had More Fatal Accidents Than Any Other Month

More fatal accidents occurred in October than any other month, making it the deadliest month for Texas drivers. A total of 941 deadly crashes happened in October from 2018 to 2020. That accounts for 9.3% of all fatal accidents.

November had the second-highest number of fatal accidents, at 912, while December was third, at 909. That indicates that the months leading up to winter carry the highest risk of fatal car crashes for Texas drivers.

Driving Safely Protects You, Others and Your Wallet

Safe driving can benefit you in more ways than one. Aside from keeping you and others around you safe, it can also help you save money over time by avoiding costly medical bills. However, accidents may happen when you least expect it, so it’s important to still get car insurance coverage. In particular, a cheap full coverage auto insurance policy can help you cover your expenses if you get into an accident.

The average cost of auto insurance in Texas is $1,316 annually, but this can vary by county and city. Case in point, we found that auto insurance in Houston costs an average of $1,560, while car insurance in Lubbock averages $1,096 per year — a difference of $464.

Note that MoneyGeek’s data are simply averages — which means your costs can change based on a range of factors, such as your age, location, driving record, type of car driven and more. To get the most affordable auto insurance, get quotes from several providers and choose the best and cheapest offer for your needs.
