Driver Driving a Car While Using Marijuana

Yes, Iowa law makes it illegal to drive with any amount of THC in your system.

Drivers who are under the influence of marijuana may have slower reaction times, impaired judgment, and compromised motor coordination skills. In other words, drivers who have recently used marijuana may be more likely to cause an accident. For this reason, it is illegal to drive under the influence of marijuana, just as it is illegal to drive under the influence of alcohol or other drugs in Iowa.

How to Know If a Driver Is High

There is no simple test for determining whether a driver is under the influence of marijuana. Without the benefit of a test like a breathalyzer that is used in suspected drunk driving accidents, police and accident lawyers must look to other evidence. Other evidence may include:

  • Observations about the driver. The police officer who responds to the accident, you, and any accident witnesses may witness the behavior of the other driver. If the driver’s behavior is consistent with a driver who is high, then it could be relevant evidence in your accident case.
  • Analysis from a Drug Recognition Expert. Some police officers are trained in drug recognition. They may be able to examine a driver’s eyes to determine if the driver is likely under the influence of drugs.
  • Driver and witness testimony. Experienced car accident lawyers know what questions to ask the driver, under oath, and other witnesses who may have seen the driver use marijuana before driving.
  • Drugs in the car. If police find marijuana in the vehicle and the driver behaves like someone who is high, then it could be relevant evidence in your car accident case.

Together, this evidence may help you know what caused your crash even without a conclusive test being administered to the driver.
