Speed limits are probably the last thing that comes to mind when traveling to an interesting place such as the U.S. state of Montana. However, the state’s traffic authority sets out clear guidelines that must be followed in order to avoid getting a traffic ticket, points added to your license, and subsequent insurance increases, or, worse, jail time!

If you are moving to Montana from another state, visiting or relocating from another country, or simply driving through the state, knowing what is the speed limit in Montana is extremely pivotal knowledge to have.

What is the speed limit in Montana

Knowledge of the correct speed limits is not only about avoiding punishment. It is also about driving safely on the roads to prevent accidents with another motorist. Driving within the speed limit helps reduce the possibility of crashes and promotes efficient use of the road.

Traffic laws, including speed limits and other motor vehicle-related laws, are established by the Montana Department of Transportation. The state speed limits are defined by two different types of speed limits, basic speeding Montana law, and absolute speed limits.

The basic speeding law prohibits driving “at a speed greater than is reasonable and prudent under the conditions and having regard to the actual hazards then existing”. This quote means that motorists must always drive at a safe speed for the conditions and environment they are driving in.

An example would be that if you were driving on a 75 mph road on a windy, dark, and snowy evening, you would be required to slow down your speed to significantly less than the signed speed limit of 75 mph. This is because the weather and road conditions would be considered dangerous, and if you were caught driving at the signed limit, you may be slapped with a fine.
