| What direction (left/right) do you stay on in a roundabout? | Keep right of the center island. Travel around the circle until your reach your desired street, then use your right turn signal and exit the roundabout. |
| When entering a roundabout yield to... | Vehicles & bicyclists within the circulating roadway |
| Saftey check before entering roundabout... | Look left to see if there is an approaching gap in traffic |
| Saftey check before turning at an intersection | Use the left-right-left rule
(Look to your left first, because vehicles coming from the left are closer to you. Then look to your right. Then look to your left again) |
| Intersection | Road junction where 2 or more roads cross over or merge on the same level (“at grade”) |
| Interchange | Road junction where 2 or more roads cross over or merge at different levels |
| The 3 types of intersections: | Controlled, uncontrolled, and blind intersections |
| The 3 types of interchanges: | Diamond, cloverleaf, and stack interchanges |
| Controlled intersections | Have signs, signals, and/or pavement markings
(Usually controlled by stop sign, yield sign, or traffic signal) |
| Uncontrolled intersections | Have no traffic control systems to determine right of way |
| Right-of-way rules for uncontrolled intersections: | 1. The vehicle that arrived first has right-of-way
2. If they arrive @ same time, the one on the left must yield
3. Drivers turning left must yield to oncoming traffic always
4. If both vehicles are turning left, they can turn w/o yielding
5. Yield to oncoming traffic & pedestrians already in or about to enter the intersection
UNCONTROLLED T-INTERSECTIONS HAVE DIFFERENT RULES: The vehicle on the terminating road (road that ends) must yield to all traffic + pedestrians unless otherwise signed |
| Blind intersections | Intersections where you cannot see 100ft in either direction during the last 100 ft before crossing due to obstacles like trees, buildings, hills, sharp curves. Have a limit of 15 mph. |
| Saftey tips for blind intersections: | 1. If unsure whether or not to yield, yield just to be safe
2. Honk your horn to alert other drivers of your presence
3. Listen for oncoming traffic
4. Turn on turn signals early to give extra warning
5. Inch forward gradually; scan the area, give yourself time to stop if another vehicle appears |
| The 3 types of interchanges are... | 1. Diamond interchange

3. Blind intersection |
| An interchange is... | A road junction where 2 or more roads cross over one another at different levels |
| Uncontrolled intersections... | Have no traffic control systems to determine right of way |
