1. Minimum speed

A minimum speed is the slowest speed you're legally allowed to drive on certain roads — especially highways or expressways. Driving Below the Minimum Speed Can be dangerous, especially if cars behind you are moving much faster. It may result in a ticket or fine unless you have a valid reason (like bad weather or mechanical issues).

  • Keep traffic flowing smoothly.
  • Prevent slow drivers from causing traffic jams or accidents.
  • Make sure vehicles don’t block faster-moving traffic.
  • Not all roads have minimum speed limits.
  • In poor conditions (rain, fog, snow), you should always slow down—even below the minimum—if it's safer to do so.
