The South Dakota move over law requires you to get out of the way of stopped vehicles with warning lights. If the stopped vehicle shows amber, yellow, or blue lights, you either merge into the lane farthest from it or slow to at least 20 mph below the posted speed limit, starting 300 feet before you reach it. If the stopped vehicle is an emergency vehicle showing red lights, you must come to a complete stop. A standard violation is a Class 2 misdemeanor with a minimum fine of $270, and causing a crash bumps the charge to a Class 1 misdemeanor carrying up to a year in jail.
Which Stopped Vehicles the Law Covers
SDCL 32-31-6.1 sorts covered vehicles by the color of their warning lights.1South Dakota Legislature. South Dakota Codified Laws 32-31-6 Through 32-31-6.2 – Duty of Other Motorists
Red lights mean an authorized emergency vehicle: police, ambulance, fire, and similar vehicles stopped at a traffic stop, crash, or roadside emergency.
Amber, yellow, or blue lights pick up a much broader group of vehicles stopped on or occupying the shoulder: tow trucks, highway maintenance crews, utility service vehicles, DOT equipment, and private contractors doing authorized roadwork. Ownership doesn’t matter. If those lights are flashing on a stopped vehicle, the rule applies.
Merging on a Multi-Lane Highway
On an interstate or any highway with two or more lanes going your direction, you must move into the lane farthest from the stopped vehicle, and you must begin that merge at least 300 feet before you reach it.1South Dakota Legislature. South Dakota Codified Laws 32-31-6 Through 32-31-6.2 – Duty of Other Motorists
The statute says “farthest,” not “adjacent.” On a three-lane road where the stopped vehicle is on the right shoulder, sliding from the right lane to the center lane isn’t enough if the far-left lane is open. Move as far away as traffic safely allows.
Slowing Down on a Two-Lane Road
When there’s no second lane to merge into, you slow down instead. The reduction is specific: at least 20 miles per hour below the posted speed limit, with the slowdown starting at least 300 feet before you reach the stopped vehicle.1South Dakota Legislature. South Dakota Codified Laws 32-31-6 Through 32-31-6.2 – Duty of Other Motorists
If the limit is 55 mph, you need to be at 35 mph or less by the time you pass. On roads posted at 20 mph or below, you must slow to 5 mph. Easing off the gas isn’t compliance; the law sets a hard number.
Stopped Emergency Vehicles With Red Lights
When the stopped vehicle is an authorized emergency vehicle displaying red lights, neither merging nor slowing is enough. You must come to a complete stop before reaching it. You can only proceed once you’ve determined it’s safe, and then only with caution. This applies regardless of road type or number of lanes.1South Dakota Legislature.

Fine and Jail for a Standard Violation
A violation of SDCL 32-31-6.1 is a Class 2 misdemeanor. The statute itself sets a minimum fine of $270. The Class 2 ceiling is a $500 fine, up to 30 days in county jail, or both.1South Dakota Legislature. South Dakota Codified Laws 32-31-6 Through 32-31-6.2 – Duty of Other Motorists2South Dakota Legislature. South Dakota Code 22-6-2 – Misdemeanor Penalties
The $270 floor is built into the statute, so a judge can’t reduce it to a token amount. Jail time is uncommon for a first offense, but it’s on the table, and repeat violations or dangerous conduct near roadside workers make it more likely.
What Happens If You Cause a Crash
Hitting a covered vehicle while violating the move over rule bumps the offense up to a Class 1 misdemeanor under SDCL 32-31-6.2. The escalation covers two scenarios: striking a stopped emergency vehicle with red lights, or striking any vehicle with amber, yellow, or blue warning lights that is stopped or on the shoulder.3South Dakota Legislature. South Dakota Code 32-31-6.2 – Occupying Highway Shoulder or Stopped Accident Caused Penalty
A Class 1 misdemeanor carries up to one year in county jail, a fine of up to $2,000, or both.2South Dakota Legislature. South Dakota Code 22-6-2 – Misdemeanor Penalties Striking an emergency responder or maintenance crew also creates civil exposure for injuries and property damage on top of the criminal case.
Points, License Suspension, and Insurance
South Dakota uses a point system for moving violations. License suspension kicks in automatically at 15 points within any 12 consecutive months, or 22 points within any 24 consecutive months.4South Dakota Legislature. South Dakota Code 32-12-49.2 – Point Accumulation Subjecting License or Permit to Suspension
Suspension length grows with repeat suspensions: 60 days for a first, six months for a second, and one year for a third or any after that.5South Dakota Legislature. South Dakota Administrative Rule 61:18:02 – Point Accumulation
A conviction also tends to raise auto insurance premiums. Rate increases from a moving violation generally run for several years, and the hit compounds if you already have other violations on your record.
Extra Risk for CDL Holders
Commercial drivers face more than the standard penalties. South Dakota treats several traffic offenses as “serious traffic violations” for CDL purposes, including failure to stop or yield, reckless driving, and improper lane changes. If a move over violation fits one of those categories, CDL disqualification applies on this schedule within a three-year window:
- Second conviction: 60-day CDL disqualification
- Third or subsequent conviction: 120-day CDL disqualification
For a driver whose job depends on an active CDL, even 60 days off the road can mean serious lost income.6South Dakota Truck Information. CDL Disqualification or Cancellation
