A Guide to Missouri’s Speeding Laws

speeding ticket is a common penalty for drivers who exceed allowed limits. To help you avoid an inconvenient expense and potential penalties, here’s some information regarding speed laws in the state.

What Are Missouri’s Laws About Car Speed?

Missouri has several statewide speeding regulations, the first of which states that drivers are required to travel at speeds that don’t endanger others. According to the state’s basic speeding law, specific limits are determined by surrounding conditions. A permitted speed on a rural road in broad daylight may not be considered safe by an officer after dark.

Posted signs typically dictate permitted speeds. However, like many states, Missouri does set absolute speed limits. If there are no roadside signs in sight, stay below these speeds:

  • 25 mph on streets in cities, towns, and villages
  • 20 to 25 mph in school zones, as posted
  • 55 mph on state two-lane “lettered” roads
  • 60 mph on interstate highways, freeways, and urban expressways
  • 65 mph on rural expressways
  • 70 mph on rural interstates and freeways

What Are the Penalties for Different Offenses?

speeding ticketIf an officer determines a driver violated the basic speeding law, the driver may be charged with a class B misdemeanor with a maximum fine of $1,000. First-time violators could also face up to a year in jail, as well as mandatory traffic school attendance.

Violation of an absolute speed limit is a class C misdemeanor, with penalties of up to 15 days in jail and $750 in fines. If you receive a speeding ticket for going less than five miles over the limit, however, the offense is only an infraction rather than a misdemeanor and carries lighter penalties.

Depending on your driving record and the speed at which you traveled when you received the ticket, you could have penalty points added to your license. Voluntarily attending an approved traffic school course may help reinstate a lost license and clear a driver’s record.
