Study Notes
Identifying Intersections
- Clues for recognizing an intersection include street signs and streetlights.
- Controlled intersections feature traffic signals to manage flow.
Intersections and Traffic Signals
- The point where stopping is unsafe is referred to as the "point of no return."
- Two types of signs commonly used to control intersections are stop signs and yield signs.
Yield and Turn Regulations
- Yield signs indicate controlled intersections where caution is required.
- Left turn arrows indicate a left turn light, which can assist in navigation through controlled intersections.
Traffic Light Indicators
- A traffic light that has been green for an extended period is likely stale and may soon turn yellow.
- If left turns are allowed but there is a left turn arrow, treat the scenario as an unprotected left turn.
Right Turns on Red and Railroad Crossings
- Right turns on red are permissible if approached as if at a stop sign.
- Red lights and crossing gates signify controlled railroad crossings for safety.
Uncontrolled Intersections
- An uncontrolled intersection lacks traffic signs and signals, requiring drivers to use caution.
- When two vehicles arrive at an uncontrolled intersection simultaneously, the driver on the left must yield to the driver on the right.
Proper Yielding Practices
- Approach an uncontrolled intersection as though encountering a yield sign, assessing traffic carefully.
- While waiting to turn left from a four-lane street without signs or signals, wait until traffic is clear before proceeding.
Railroad Crossing Indicators
- Railroad crossings are marked by a white, X-shaped sign for awareness.
Advantages of Roundabouts
- Roundabouts are safer due to all traffic moving in the same direction, avoiding left turns across intersections, and implementing yield signs to minimize delays.
Right of Way Concepts
- The right of way involves allowing others to proceed before you.
- You only have the right of way when other drivers voluntarily grant it to you.
- Yielding means other drivers should not need to slow down or stop for you.
Emergency Vehicle Protocol
- When an emergency vehicle with sirens or lights approaches, yielding the right of way is mandatory.
Judging Traffic Gaps
- Entering traffic at an intersection requires careful judgment of the gap size between vehicles.
- Accelerating to 30 mph while turning left takes about seven seconds.
Joining Traffic
- Turning right into traffic requires a larger gap than simply crossing through the intersection.
- When turning left, the gap needed to the left should be larger compared to right turns for safety.
