Study Notes
Intersection Basics
- An intersection is where two or more roads meet and can be controlled (with traffic signals) or uncontrolled (without signals).
- Street signs and traffic lights signal the presence of an upcoming intersection.
Safety Considerations
- "The point of no return" is the location where stopping safely is no longer an option.
- At a controlled intersection, traffic signals and signs dictate the flow of vehicles.
Traffic Control Devices
- Two kinds of signs control vehicle movements: stop signs and yield signs.
- A yield sign indicates a controlled intersection, requiring drivers to give way to cross traffic.
- Traffic signals can include special lights for left turns, and a green light after a delay indicates a fresh signal.
Traffic Light Types
- A stale green light has been on for a while and may soon change.
- A fresh green light has just activated, allowing drivers to proceed.
- An unprotected light indicates that the turn is not guaranteed; treat it as an unprotected left turn.
Right-of-Way Rules
- A delayed green light means one side of the intersection has a green light while the other side is red.
- Right turns on red are allowed, but drivers must treat the situation like coming to a stop at a stop sign.
- Uncontrolled intersections and railroad crossings may lack traffic signals but typically have signage like cross bucks and flashing lights.
School Bus Protocol
- When following a school bus near a railroad crossing, always be prepared to stop.
Traffic Gap Requirements
- To cross safely on a street with traffic moving at 30 mph, a driver requires a 2/3 block gap in each direction.
- When turning and merging into traffic, the faster the oncoming traffic, the larger the gap needed for a safe entry.
General Intersection Behavior
- At controlled intersections, drivers must yield the right-of-way to others as dictated by traffic controls.
- When approaching a stop sign, assess traffic gaps in all directions before proceeding.
