Question

Difficulty: MediumRegulatory Signs

A driver turning onto a main street may legally use a shared two-way left-turn lane—designated by regulatory signs and pavement markings—as an acceleration lane to gain speed and merge into high-speed traffic.

Answer: Answer

Answer

The statement is false. Shared two-way left-turn lanes are reserved exclusively for left-turn maneuvers, not for traveling down the roadway or accelerating to merge with traffic.
The statement is false because regulatory rules prohibit using a shared center two-way left-turn lane for driving through or accelerating to merge. Drivers exiting a driveway or side street may turn into the lane and stop if necessary to wait for a gap in traffic, but must not drive along the lane to build speed.

Step-by-Step Solution

1
Identify the regulatory sign and lane rule for two-way left-turn lanes.
Two-way left-turn lanes marked by regulatory signs are meant to isolate left-turning vehicles from through traffic.
Regulatory signs and double solid/dashed yellow lines establish the exclusive legal use of the designated lane.
2
Evaluate the driver action described in the statement.
Driving down a center turn lane to accelerate and match traffic speed creates a severe collision risk with opposing vehicles using the lane to turn.
Because opposing traffic shares this single lane, using it as an acceleration lane violates traffic regulations.
