What is the definition of a controlled intersection?
Answer: D — An intersection that has signs and signals
A controlled intersection is defined as an intersection that has signs and signals. Signs can include stop signs, yield signs, or other regulatory signs, while signals typically refer to traffic lights. These additions help regulate the flow of traffic, indicating when to stop, yield, or proceed, thus improving safety and traffic control. This differs from an uncontrolled intersection where there are no signs or signals to dictate right of way, potentially leading to confusion and accidents.
