TRAFFIC SIGNS BIKE SAFETY VEHICLES SAFETY QUIZ Traffic Signs Stop Sign This sign is one of the most well known, as well as one of the most common. As you might expect, this sign tells a driver to stop and check for traffic before continuing. 4-Way Sign Sometimes, this will appear below a regular stop sign. It means that vehicles coming from each direction must stop before moving on. The first car to stop at the sign has the right-of-way, which means they can go on. All Way Sign This sign works just like the 4-way sign. The only difference is this sign will appear when there is more (or less) than four streets coming together at one intersection. Yield Sign Another common sign is the yield sign. Its purpose is to tell drivers to look out for other cars, but they don't have to stop if there is no one coming. Speed Limit These signs are seen almost everywhere in the state. It tells drivers the fastest they can safely drive on a road. There are many factors that affect the speed limit of a road. The only place in the state to go 75mph is the interstate. Minimum Speed This sign is the opposite of the speed limit sign. Sometimes it is also unsafe to go too slow, so this sign tells drivers to maintain at least a certain speed. Night Limit On some roads in the state, it is safe to travel a faster speed during the daylight than in the dark. In this case, the black sign will warn drivers of the dangers of driving too fast in the dark. Truck Limit Sometimes, especially in hilly areas, large trucks must travel slower than the rest of the traffic. This is because it takes them longer before they can stop. This sign tells them how fast they are able to go. Speed Zone Ahead On the highway, it takes a long time to slow down. This sign tells drivers that there will be a need to change their speed coming up. It helps because they can gradually slow down instead of slamming on the brakes. No Left Turn In some places it is unsafe to turn left at an intersection. This sign makes it clear that you cannot turn left at this point in time. No Right Turn Just like the No Left Turn sign, this sign tells drivers when it is unsafe to make a right turn. No Bicycles This sign tells anyone riding their bicycle that it is unsafe to take the road any further. There is always a reason for these signs and bike riders must pay attention and avoid the road. Do Not Enter Look out when you see this sign! It indicates that the vehicle may be heading the wrong way on a one-way street. This is especially dangerous because accidents are likely when going right into oncoming traffic. Wrong Way Just like the Do Not Enter sign, this is an important one to look out for. It tells the driver that they have already begun to go the wrong way and they must turn around immediately. One Way This is an early warning to drivers that the traffic on a road is only allowed in one direction. The arrow will point with the flow of the traffic. If the driver carelessly misses one of these signs, they are sure to see the Wrong Way sign above. Keep Right On long, steep hills, sometimes an extra lane will be added to the road for cars and trucks that go very slow up the hill. This sign tells those slow vehicles to keep right, and out of the way of the others. Left Lane Must Turn Sometimes, a lane gets divided off of the main road. In this case, vehicles travelling in that lane must go that way. This sign warns the driver to change lanes if they want to continue going straight. Right Lane Must Turn This is exactly the same as the Left Lane Must Turn sign except it tells vehicles in the right lane that they are going to go right unless they change lanes. No Parking There are places in town where vehicles are not allowed to park. It may be because of a fire hydrant or an unloading zone. This sign lets drivers know not to park in these areas. No Parking This sign looks a little different, but it means the same thing as the No Parking sign above. 2-Hr Parking In business district of some South Dakota cities, vehicles are only allowed to park for two hours during business hours. This sign indicates where these two hour zones are located. Handicapped Parking Some parking spaces are reserved for people with disabilities. They are usually the spaces near the front of a building so a handicapped person doesn't have to go so far. Without a sign, no one can park here.
