What is the purpose of the service or brake check signs that show a truck escape ramp a mile or two ahead?

• A.To indicate a weigh station entrance
• B.To warn of a toll plaza
• C.To mark a rest area for all vehicles
• D.To let a driver plan early: a ramp is an option to commit to in time, not a surprise to swerve for at the last second

Why

Advance signs convert a panic swerve into a planned maneuver with signaling and lane position settled early. Drivers descending with marginal brakes should be tracking those signs from the summit onward.
