In Idaho, vehicle crash statistics for 2023 show that approximately 24,000 traffic crashes were reported statewide, resulting in more than 10,000 injuries and 275 traffic fatalities. Although Idaho has a relatively small population, rural highways and high-speed roadways contribute to a disproportionately high fatality rate. The majority of deadly crashes occurred on rural roads, where higher speeds, longer emergency response times, and limited roadway lighting increase crash severity. Speeding, impaired driving, distracted driving, and failure to wear seatbelts remained the leading contributing factors in fatal accidents. Single-vehicle roadway-departure crashes accounted for a significant share of traffic deaths, particularly on two-lane rural highways. Motorcyclists, pedestrians, and bicyclists also faced elevated risks, while commercial vehicle traffic on major corridors such as I-84 and I-15 contributed to severe multi-vehicle collisions. Overall, driver behavior, rural road conditions and high-speed travel continued to be the primary factors influencing roadway fatalities and serious injuries across the state.
Passenger car occupants accounted for 80 fatalities (29%) of all traffic-related deaths in Idaho.
Motorcyclists were involved in 39 fatalities (14%), highlighting the elevated risk for motorcycle riders on Idaho roads.
Occupants of light trucks and SUVs recorded the highest number of fatalities at 96 deaths (35%), making this the most affected vehicle category statewide.
Bus and public transportation-related crashes resulted in 7 fatalities (3%), representing a very small portion of total traffic deaths.
Semi-trucks and tractor-trailers were involved in 13 fatalities (5%) of Idaho's total crash deaths.
Pedestrian fatalities reached 31 deaths (11%), underscoring the vulnerability of pedestrians in traffic environments.

A car accident can be overwhelming and stressful, even if it's minor. Knowing what steps to take immediately afterward can help protect your health, your legal rights, and your financial interests. Here are five essential things to do after an accident:
Your safety comes first. Check yourself and others for injuries and call 911 immediately if anyone is hurt. Even if injuries seem minor, it's important to get medical attention, as some symptoms may not appear right away. If possible, move to a safe location away from traffic while waiting for help to arrive.
Always report the accident to the police. An official police report creates an objective record of what happened, which can be critical for insurance claims and legal matters. Cooperate with the officer, provide accurate information, and avoid admitting fault at the scene.
If it's safe to do so, gather as much information as possible. Take photos or videos of the vehicles, damage, license plates, road conditions, traffic signs, and any visible injuries. Exchange contact and insurance information with the other driver(s) and attempt getting contact details from any witnesses in the area.
Even if you feel fine, consider seeing a medical professional as soon as possible. Injuries such as whiplash, concussions, or soft-tissue damage can take hours or days to show symptoms.
Report the accident to your insurance provider promptly and provide them with accurate details. Stick to the facts and avoid speculation. Keep copies of all documents related to the accident, including medical bills, repair estimates, and correspondence with insurers.
No fishing while riding an animal: This particular law forbids fishing off the back of a camel or a horse. One must wonder what spurred on this oddly specific law into fruition.
The No Smiling After Dark Law: In Pocatello, Idaho, there is an old ordinance that technically makes it illegal to look gloomy or frown in public, with a related law that prohibits smiling in certain circumstances after dark. This law is part of Pocatello’s light-hearted, tongue-in-cheek ordinance of 1948 (Ordinance No. 1100). This law was enacted in 1947 during an exceptionally brutal winter and was meant to lift people’s spirits; however, it is not actively enforced.
The No Driving Without a Windshield Law: In Idaho, it is illegal to operate a motor vehicle on a public road or highway without a properly installed and functioning windshield that provides adequate protection and visibility for the driver. This is considered a safety issue and Idaho law enforcement officers will pull you over and cite drivers operating vehicles without proper safe or undamaged windshields.
The Horse and Buggy Road Law: In Idaho, horse-drawn vehicles are legally permitted to be used on most public roads and are subject to the same basic traffic laws and regulations as motor vehicles. Horses and Buggies have the same requirements for lighting during nighttime travel and adherence to posted speed limits and traffic control devices as the rest of the vehicles.
The No Hitting a Pedestrian with a Car Law: In Idaho, it is obviously and explicitly illegal to intentionally strike a pedestrian with a motor vehicle on a public road or in a public place. While this seems like the most blindingly obvious and fundamentally necessary traffic safety regulation ever committed to paper in the history of American legislation, the fact that Idaho state law felt it necessary to specifically and explicitly address intentional pedestrian vehicle contact as a distinct legal category suggests that Idaho lawmakers were determined to leave absolutely no ambiguity whatsoever about the legal status of deliberately striking a pedestrian with your car.
The No Carrying a Concealed Weapon While Drunk Law: In Idaho, it is illegal to carry a concealed weapon while under the influence of alcohol or drugs, including in a motor vehicle on a public road or highway. While Idaho has some of the most permissive concealed carry laws in the entire United States, the state draws a very clear legal line at the combination of concealed weapons and intoxicated motor vehicle operation.
The Snowmobile Road Law: Idaho Code Title 67 allows snowmobiles to legally cross public roads and highways at designated crossing points. This is only permitted during the snowy winter months. Snowmobile riders are strictly prohibited from traveling along public roads or highways for extended distances except in specific circumstances and designated areas. Given the extraordinary importance of snowmobiles as a primary mode of winter transportation in many of Idaho's remote and mountainous communities during the long winter months, this law represents a careful and thoughtful balance between the legitimate transportation needs of Idaho snowmobile users and public safety.
The No Driving While Distracted Law: Similar to most other states in the country, Idaho has a distracted driving law making it illegal for any driver to engage in any activity that distracts them from the primary task of safely operating their motor vehicle on a public road or highway. While Idaho's distracted driving laws are considered less comprehensive and strictly enforced than those of some other states, the law still carries significant fines for drivers caught engaging in unsafe behaviours like texting while driving.
The No Driving a Vehicle with Faulty Brakes Law: In Idaho, it is illegal to operate a motor vehicle on a public road or highway with brakes that are known to be faulty, inadequate or not in proper working condition under Idaho state traffic law. Brakes are amongst the most important safety equipment in any vehicle and it is vital that they are maintained and are in perfect operational condition while the vehicle is in motion. Idaho law enforcement officers have the authority to pull over and inspect any vehicle they suspect to have inadequate or faulty braking systems. Drivers found operating vehicles with faulty brakes can face significant fines and be required to immediately remove their vehicle from public roads until all necessary brake repairs are made.
The Move Over Law: Under Idaho Code Section 49-1425, all drivers are legally required to move over one lane or reduce their speed significantly when passing any emergency vehicles, such as law enforcement vehicles, tow trucks or roadside assistance vehicles that have stopped on the side of the road with their lights flashing. Failure to comply with Idaho's Move Over Law can result in significant fines and is considered one of the most seriously enforced traffic safety laws in the state.
Motorcycle age restriction: In Idaho Falls, it is strictly illegal for anyone over the age of 88 to ride a motorcycle on public roadways within city limits. While some may argue that this law may violate the rider’s rights, the local government cites it as a safety measure.
The No Street Racing Law: Under Idaho Code Section 49-1401, it is strictly illegal to participate in or organize any form of motor vehicle racing or speed competition on a public road or highway. Idaho takes its street racing laws extremely seriously and enforces them with significant penalties, including substantial fines, mandatory license suspension and potential vehicle impoundment for drivers caught participating in illegal street racing on Idaho’s public roads.
Indecent Exposure Ban: The state of Idaho is one of the few states to expand their indecent exposure statute to apply to signs and vehicle accessories such as “truck nuts”.
The Agricultural Vehicle Road Law: In Idaho, agricultural vehicles and equipment are legally permitted to use public roads and highways for the purpose of moving between fields and farming locations, subject to specific speed limits, lighting requirements and road use regulations. Recognizing that agriculture and farming remain one of the state’s highest sources of revenue, this legislation aims to ensure the safe coexistence of farm equipment and regular motor vehicle traffic on Idaho's extensive rural road network.
