A sign at an exit ramp reads 'RIGHT LANE MUST EXIT.' A driver wants to continue on the highway. What should they do?

LANE CONTROL REGULATORY SIGNS: 'RIGHT (OR LEFT) LANE MUST TURN/EXIT' signs are regulatory — they require that traffic in the specified lane perform the indicated action (turn or exit). DRIVER RESPONSE: If you want to continue on the highway, move LEFT out of the right lane before the mandatory zone begins (usually several hundred feet before the intersection or exit). If you are in the right lane and the sign applies, you are required to exit — proceeding straight is a violation; ADVANCE PLANNING: Look ahead for lane designation signs; change lanes smoothly when safe; don't force a last-minute lane change by waiting until the mandatory zone begins. SIMILAR SIGNS: 'LEFT LANE MUST TURN LEFT'; 'TURN ONLY' (on pavement); overhead lane-use signs above each lane.
