Question

when passing on the expressway, it is generally safer to pass *
in the center lane
for any available lane
on the right
on the left

grade elevation refers to *
raising the suspension of a vehicle
giving extra credit in drivers education class
using bridges and tunnels to direct traffic over and under other travel lanes
adding gravel to the shoulder of roads

a yellow x on an overhead signal above your lane indicates *
you are in an express lane
the lane will be closed farther ahead
you are going the wrong way
the lane is now closed to traffic

Explanation:

Analyze passing rules on expressways

The first question asks about the safest way to pass on an expressway. Standard defensive driving guidelines state that passing on the left is generally the safest and most predictable maneuver because drivers expect faster traffic and passing vehicles to come from their left. Passing on the right is discouraged due to larger blind spots on the right side of vehicles.

Define grade elevation

The second question asks for the definition of "grade elevation" (often referred to as grade separation in Expressway Interchange Types). In civil engineering and traffic safety, grade separation or elevation refers to using bridges, overpasses, or tunnels to direct traffic over or under other travel lanes to prevent conflicts.

Interpret overhead lane signals

The third question asks about the meaning of a yellow X on an overhead signal. In Expressway Lane Closures and lane-use control signals, a steady yellow X indicates that the lane you are in is about to be closed or that the signal is about to change to a red X, meaning you must safely vacate the lane as it will be closed farther ahead.
