Basic Intersections
What is the safe action you should take as you approach any intersection to give yourself more time to search the area and stop smoothly?
Adjust your speed to allow more time to search the area and make a smooth stop if needed.
What is the only highway warning sign that is circular in shape?
Railroad advance-warning sign (the circular warning sign).
In what direction does traffic circulate inside a roundabout in the U.S.?
Counterclockwise.
Give two reasons why complex intersections present higher risk than simpler intersections.
Higher traffic volumes and multiple turning lanes; many intersecting conflict points increase crash risk.
What is an interchange?
a point at which a driver can enter or exit an expressway or connect with a highway going in another direction
At a four-way stop, if multiple drivers arrive at the same time, which driver has the right-of-way?
The driver on the right.
How close should you stop to a railroad crossing when a train is approaching? (give the minimum distance)
Stop no closer than 15ft from the nearest rail.
When approaching a roundabout, what two actions must you do before entering?
Slow down and yield to traffic in the roundabout; turn on your right turn signal (signal one street before exit).
What type of collision accounts for more than one-third of all deaths to vehicle occupants and commonly occurs at intersections?
Side-impact (T-bone) collisions.
Name the three main components of an interchange.
Through lanes, speed-change lanes (acceleration/deceleration), and ramps.
Define a T-intersection and explain which driver yields there.
A T-intersection is where one road ends and meets another road forming a "T." The driver on the road that ends yields to traffic on the through road unless posted otherwise. "Give way to the right" rule does not apply
List three actions you should take to determine whether it is safe to cross railroad tracks that have no lights or gates.
Slow down and scan for warning lights/gates; look and listen both directions for trains; if uncertain, stop, look, and listen before crossing.
How should you navigate a one-lane roundabout when making a left turn?
Enter the roundabout with a right turn, yield to circulating traffic from the left, go around the center island, then make a right to exit at the desired street (completing the left by circling).
Name three special challenges elderly drivers face at complex intersections.
Slower processing of complex signals/lane markings; more difficulty judging gaps and speed; higher rates of failing to yield or making improper turns.
Which interchange type is typically chosen for lower-traffic locations: diamond, cloverleaf, or trumpet?
Diamond interchange.
Name three things you should scan for to manage visibility at an intersection.
Scan all four corners for signs, signals, pavement markings, roadway features, motorized vehicles, and nonmotorized users (pedestrians, bicycles); check areas of blocked vision.
If your vehicle stalls on the tracks and no train is visible, what two steps should you attempt in order? (short answer)
Check both directions for trains and try to restart the engine; if the vehicle will not start and no train is visible, try to push the vehicle off the tracks.
For a two-lane roundabout, where should you enter and exit relative to the lane you chose on approach?
Enter and exit in the same lane you used on approach (inside lane to inside lane, outside lane to outside lane).
When using designated left-turn lanes with a left-turn arrow and a blinking yellow arrow, what is the driver expected to do on a blinking yellow arrow?
Yield to oncoming traffic; the blinking yellow arrow means proceed with caution and yield to oncoming traffic before turning.
Why are speed limits often lower on ramps connecting to and from freeways? (brief explanation)
Because ramps often have sharper curves and shorter sight distances, requiring lower speeds for safe maneuvering and to save land.
For a typical 30-foot-wide intersection with cross traffic at 30 mph, how many seconds are recommended to cross for (a) normal and (b) maximum safety? (Write both values.)
Normal: 6 seconds; Maximum safety: 8 seconds.
After a train passes at a multi-track crossing, what must you always do before proceeding?
Check in both directions to ensure no other trains are coming (especially on multiple tracks) before proceeding.
State two differences in how you handle one-lane vs. two-lane roundabouts (focus on lane choice and lane changes).
One-lane: yield to traffic and merge; no lane changes inside; two-lane: choose inside or outside depending on exit, yield to circulating traffic, do not change lanes inside the roundabout.
Provide four best strategies for dealing with pedestrians at complex intersections.
Yield the right-of-way to pedestrians; never pass a vehicle stopped for pedestrians; expect the unexpected; be alert and check blind spots.
Describe a cloverleaf interchange and one major advantage it provides compared to at-grade intersections.
Cloverleaf: four loop ramps allow directional changes via loops, providing nonstop access between two busy roads and eliminating at-grade crossing conflicts.
