South Dakota Car Crash Statistics

South Dakota presents a unique landscape for motorists, marked by its extensive rural roads and notable highways. The state experiences a high percentage of crash deaths on these rural roads, second only to Vermont in the United States. In 2021, a staggering 82% of motor vehicle crash deaths in South Dakota occurred in rural areas, underscoring the significant risks faced by drivers outside urban centers. Several factors contribute to the high incidence of traffic collisions in the state. Weather conditions, including snow and ice, often deteriorate road conditions, making driving hazardous. Additionally, South Dakota's rural nature means that emergency response times can be longer, potentially affecting the outcomes of accidents.

The state's highways, while picturesque, are also the scenes of many car accidents, with Interstate 90 being particularly noteworthy. Here, traffic volume and speeds combine to increase the likelihood of collisions.

What Should I Do After a Car Accident in South Dakota?

After a car accident in South Dakota, you should follow these steps to ensure compliance with state laws and safeguard your interests:

1
Stop and Stay at the Accident Scene

It's crucial not to leave the accident scene. Ensure you're safely off the road and not obstructing traffic while assessing the situation and checking for any injuries.

2
Exchange Information

You're required to share your name, address, driver's license number, and vehicle license number with the other parties involved. It's also a good idea to gather information from witnesses.

3
Provide Immediate Assistance

If there are injuries, offer reasonable help, including transporting injured parties to receive medical treatment if necessary.

4
Report the Accident

If there's injury, death, or property damage exceeding $1,000 for one person's property or $2,000 in total, you must report the accident to the police immediately.

5
Hitting an Unoccupied Vehicle

If you hit a parked car, try to find the owner, and if you can't, leave a note with your contact information and report the incident to the police.

6
Document the Scene

Take comprehensive photographs and videos of the accident scene, encompassing all vehicles involved, visible damages, road conditions, traffic signage, and any injuries sustained. This documentation can be crucial for insurance claims and potential legal proceedings.

7
Obtain a Police Report

If law enforcement responds to the accident, ensure you get a police report or at least the report number. This report will contain an unbiased third-party account of the accident, which is valuable for insurance and legal matters.

8
Seek Medical Attention

It is advisable to consult a doctor following an accident, regardless of whether you believe you are injured. Certain injuries, such as whiplash, may not manifest immediately. Medical records will also serve as evidence if you need to make an injury claim later.

9
Notify Your Insurance Company

Inform your insurance provider about the accident as soon as possible. Be honest about the incident, but be cautious about admitting fault until all facts are known. Your insurance company will guide you through their claim process.

10
Consider Legal Advice

If the accident involves significant property damage, injuries, or potential legal complications, consulting with a personal injury attorney can be beneficial. They can help navigate the claims process and ensure your rights are protected.

South Dakota Driving Laws and Facts

The state of South Dakota has stringent laws that drivers should follow when operating a car to help improve road safety. Some of these laws include:

DUI Laws

South Dakota enforces strict DUI laws, with different Blood Alcohol Concentration (BAC) limits based on age and type of license. For drivers above 21, the BAC limit is 0.08%; for commercial license holders, it's 0.04%, and drivers under 21 have a BAC limit of 0.02%. Penalties for DUI offenses vary, including fines, jail time, license suspension, and mandatory alcohol treatment programs or ignition interlock device installation for multiple offenses.

Window Tint Law

In South Dakota, window tinting regulations specify that the front windshield can only have a non-reflective tint above the AS-1 line. Front-side windows should permit more than 35% of light transmission, whereas back-side and rear windows must allow more than 20% of light transmission. Violations of these regulations are considered Class 2 misdemeanors.

Secure Load Law

The law requires that all loads being transported must be securely fastened to prevent them from becoming dangerous. Failure to secure loads properly can result in fines and, if it causes damage or an accident, more severe penalties.

Not complying with this law is considered a Class 2 misdemeanor, carrying penalties such as a minimum fine of $270.00 and/or up to 30 days in jail. If failing to move over results in a crash, it escalates to a Class 1 misdemeanor.
