South Dakota Road Signs: Fines Double Sign, Bus Rules & DMV Test
What is the "Fines Double" sign in South Dakota and where does it appear? How many attempts do you get on the South Dakota knowledge test? What are the work zone rules on I-90 and I-29? The SD Driver Licensing Division, DPS at dps.sd.gov/driver-licensing allows 3 attempts within 6 months. South Dakota uses a specific black-and-white "Fines Double" regulatory sign. listed alongside stop signs and speed limits in the official manual. Work zone fines may also be doubled. School bus stops require remaining stopped until all children are clear.

Direct traffic around obstacles or closed areas
- You must follow flagger instructions in South Dakota work zones. they direct traffic by sign or flag.
- Fines for speeding in a work zone may be doubled in South Dakota.
- The black-and-white "Fines Double" sign is a specific SD regulatory sign. recognize it and slow down immediately when you see it.
- Work zone temporary traffic signals may be used. stop at the white line when directed.
Key test point: Orange always means construction or work zone. If you see orange, reduce speed and increase following distance immediately.
9. South Dakota Railroad Crossings: Stop Behind the Line, Check for Multi-Track and Use the DOT Crossing Number
At South Dakota railroad grade crossings, you must stop behind the stop line or before the intersection clears when a train or railroad vehicle is approaching. When lights are flashing, you must stop. SD crossings with more than one track post the number of tracks. but not all multi-track crossings have these signs, so always check. DOT crossing numbers on crossing posts let dispatchers identify exact locations. use them to report problems.
Advance Warning Sign
Railroad crossing ahead. the first sign you see. Begin slowing down.
RR Crossbuck Sign (X-shaped)
Located at the crossing itself. yield to trains. Treat as a yield sign if no gates or lights.
Railroad Crossing (at crossing)
Marks the exact railroad crossing location
Crossing Gates
Lower when a train is coming. never drive around or under a lowered gate
Pavement markings (X + RR)
Painted on the road surface before the crossing as an advance warning
Flashing Red Lights
A train is approaching, stop and wait. Do not proceed until lights stop and it is fully clear.
Stop Line
Stop behind this line before the crossing; when lights flash you must stop; check for multi-track even when signs do not warn you; report problems using the DOT crossing number on the post
- The round yellow warning sign with "X" and "RR" is the first sign before an SD railroad grade crossing. slow down, look, and listen.
- The white crossbuck X sign at the crossing means stop when a train or railroad vehicle is approaching. stop behind the stop line or before the intersection clears.
- When alternating lights flash, you must stop. At crossings with gates, never drive around them.
- SD crossings with multiple tracks may post the number of tracks. but not all do. Always check for a second train before crossing after the first passes.
- Transit buses, school buses, and hazmat vehicles must stop at all crossings. Leave extra following distance when driving behind these vehicles near crossings.
- The DOT number on crossing posts identifies the exact location for dispatchers. report any obstruction or problem at the crossing using this number.
Key test point: Stop behind the stop line when a train approaches. Not all multi-track crossings post warnings. always check. DOT crossing numbers are used to report problems. All tested on the SD knowledge exam.
10. South Dakota School Zone and School Bus Rules: Stop Required Everywhere Except Physical-Barrier Divided Highways
Pentagon-shaped, fluorescent yellow-green signs mark SD school zones. Obey the slower posted speed when lights are flashing or children are present. At a school crossing with a traffic patrol officer, stop and yield if signaled. When a school bus has its red lights flashing or stop arm extended, you must stop from all directions. the only exception is when the roadway is separated by a physical barrier.
School Zone
School ahead. be alert for children, reduce speed
School Speed Limit
Obey slower posted school zone speed when lights flash or children present; at crossing with patrol, stop and yield if signaled; school bus red lights = stop all directions
Speed Limit Lights Flashing
Speed limit applies only when the flashing lights are active
School Crossing Ahead
Crosswalk used by schoolchildren ahead. yield to crossing guard and students
- In a school zone when lights are flashing or children are present, obey a slower posted speed limit. Watch for children in playground and residential areas who may run out from between parked vehicles.
- At a school crossing with a traffic patrol officer, stop and yield if signaled to do so.
- You must always stop for a school bus that has its red lights flashing or its stop arm extended. from all directions.
- Exception: The roadway is separated by a physical barrier.
- After the buss red lights stop flashing and the stop arm is no longer visible, proceed slowly and watch for children.
- Children have been known to run in front of inter-city buses and other large vehicles too. apply the same caution near any stopped bus.
Key test point: The pentagon shape is used exclusively for school signs. No other sign category uses this shape. making it one of the easiest shapes to identify on the exam.
11. South Dakota Pedestrian and Bike Signs: Bicycles Have Same Rights as Vehicles and Get Extra Space Near Children
Pedestrians have right-of-way at crosswalks in South Dakota. Bicyclists have the same rights, privileges, and responsibilities as motor vehicle operators. The SD manual specifically advises giving extra space to bicyclists. especially children on bikes who may move suddenly and without warning. Do not stop, park, or drive on designated bicycle paths. Both sign types use fluorescent yellow-green and are tested on the SD knowledge exam.
Pedestrian Crossing Sign
A marked crosswalk is ahead. watch for pedestrians crossing
Bicycle Crossing Sign
Cyclists frequently cross here. reduce speed and yield to bikes
No Bicycles
Bicycles are prohibited on this road or path
No Pedestrian Crossing
Pedestrians must not cross here
- Pedestrians always have right-of-way in South Dakota crosswalks. yield before entering the crosswalk.
- Bicyclists in SD have the same rights and responsibilities as motorists. Yield to cyclists in intersections as you would for other vehicles.
- Give extra space to bicyclists, especially children. they can move into your path quickly and without warning.
- Yield the right-of-way when a bicycle path or bike lane intersects a road. Do not stop, park, or drive on a designated bicycle path.
- Be alert for unskillful cyclists who may swerve unpredictably. if you see one, be ready for sudden movements.
- Fluorescent yellow-green is used for both school and pedestrian/bike signs. the shape distinguishes between them.
Key test point: Pedestrians always have right-of-way at crosswalks. marked or unmarked. This rule appears on virtually every state DMV exam.
12. How to Pass South Dakota Knowledge Test: 3 Attempts in 6 Months, the "Fines Double" Sign and Prairie-Specific Rules
- 3 attempts per 6-month period, $28 fee. You get three tries to pass within 6 months. After that. or after 3 failures. the period resets. Apply at any SD exam station or online at dps.sd.gov/driver-licensing.
- Know the "Fines Double" black-and-white sign. South Dakota uses a specific regulatory sign labeled "Fines Double", it is listed in the signs section alongside stop signs and speed limits. It is tested and specific to South Dakota.
- Work zone fines may be doubled. SD work zones can carry doubled fines. obey all posted work zone speed limits and flagger directions.
- School bus: physical barrier exception only. You must stop for a school bus from all directions. The only exception is a physical barrier separating the roadway. After the red lights stop and the arm retracts, proceed slowly and watch for children.
- Railroad crossings: always check for multi-track. Not all multi-track crossings post a warning sign in SD. always look for a second train before crossing. Stop behind the stop line when a train approaches or when lights flash.
- Orange triangle = slow-moving vehicle (under 25 mph). Farm tractors, animal-drawn vehicles, and roadway maintenance vehicles use this reflective orange triangle. Be prepared to slow down significantly when you see it.
- Bicyclists have equal road rights. They follow the same laws and have the same rights as motorists. Give extra space, especially to children on bikes who may move suddenly.
- Slow-moving vehicles at 35 mph on steep hills. Large trucks descending steep grades may travel approximately 35 mph and should use right lanes. plan your following distance accordingly.
- Flashing signals. Flashing red = full stop. Flashing yellow = slow and yield. Work zone temp signal = stop at white line.
- Emergency vehicle rule in SD. On two-lane highways, slow to at least 20 mph less than the posted limit (or 5 mph when posted at 20 or less) when 300 feet from a stopped emergency vehicle. Violation = Class 2 misdemeanor under SDCL 32-31-6.1.
