The Minnesota Department of Public Safety (DPS) said that there is not a law against driving with a broken foot or a foot in a cast. If your doctor told you not to drive though you should listen to their professional instructions on the use of your broken foot and it would not be recommended to drive.
The MN State Patrol told us that there is not a requirement to drive with your right foot in Minnesota so if you have a broken right foot you can try to drive with your left foot. However they advised that common sense should prevail so if you cannot drive safely with a cast on your right foot or drive with your left foot adequately then it would not be recommended for you to operate a vehicle.
If you were to cause an accident due to driving in a careless or negligent manner because of the injury to your right foot your car insurance company should still cover you however the accident would be on your driving record and likely cause your rates to rise. Also if you were to cause a serious accident you could cause more damage to your already broken foot.
As the Minnesota State Patrol noted use common sense when driving with a broken right foot. If you are unable to properly use the gas and brake pedals with your broken foot or with your left foot then find someone that can drive you around until your foot heals.
