Understanding Road Traffic Signs in South Dakota

August 22, 2024

Whether you’re cruising through familiar territory or exploring new paths, knowing your roads signs can make all the difference for a safe trip. We handpicked a handful of signs to help you the next time you hit the road. So, buckle up and let’s dive into the meanings behind the signs that keep us safe.

Back to Basics

These signs are self-explanatory, but a quick refresher never hurts.

Stop Sign

A stop sign means you must come to a stop (yes, a complete stop. We’re looking at you 🫵) and wait until crossing vehicles and pedestrians have passed by.

Yield Sign

A yield sign means you must slow down and yield to other vehicles and pedestrians that have the right of way.

Merge Sign

Merge signs signal that two lanes of traffic will come together. Drivers in merging lanes should yield to traffic in through lanes and enter when safe.

WATCH OUT, DRIVERS

BRIDGE ICES BEFORE ROAD

South Dakota’s unpredictable weather likes to keep us on our toes. And though this sign is all words and no pictures, it can still confuse drivers. Bridges aren’t insulated by the ground like roads are. So, when it’s rainy, foggy or sleeting, water on bridges will turn to ice before it will on the road. If you’re approaching a bridge, know that it could be slippery, even if the road’s not.

THINK!

South Dakota’s THINK signs act as a memorial to the victims of motor vehicle crashes — and as a reminder of the dangers on the road. Wear your seat belt, don’t speed or drive distracted or impaired.

MOUNTAIN GOAT

No, you’re not at the zoo. Crossings for mountain goats, bighorn sheep, deer and other wildlife can appear on the road – and it’s for good reason. Watch for animals on the road, especially at high speeds or when fields, hairpin curves, hills and trees make thick cover for furry friends.

WHAT’S THAT MEAN AGAIN?

LOW CLEARANCE

Low clearance signs show height restrictions for driving under bridges, overpasses, drive-thrus, parking garages and other structures. If you drive a truck or commercial vehicle, always pay attention to low clearance signs so your ride doesn’t suddenly become a convertible (we’re looking at you, Pierre train bridge).

SLOW MOVING VEHICLE

While these signs aren’t posted on the side of the road, it’s good to know what they mean. The slow-moving vehicle triangle is often seen on tractors, horse-drawn buggies and other slow-moving vehicles. When you spot one, approach slowly and proceed with caution.

SOFT SHOULDER

This road sign warns that the ground beside the pavement isn’t as firm as the road itself — think loose gravel or soft dirt. If you need to pull over, do it carefully and avoid driving onto the shoulder, because it might not support your vehicle.

STEEP GRADE

In hilly areas, steep grade signs warn drivers of a steep slope or angle, which is especially important for heavy trucks and other vehicles that need more time to slow down. Approach these areas with caution and slow down in advance to prepare for the steep drop.
