When should I prepare for a 'Must Turn Right or Left' sign?

You should prepare for this sign well before reaching it by observing lane markings and other traffic. Look for signs indicating lane assignments or directional arrows on the road surface or overhead. Early preparation ensures you are in the correct lane and can execute the required turn smoothly and safely, avoiding abrupt movements.

If you need to go straight, you must ensure you are in a lane that permits this, which would be indicated by different signage or road markings.

How does the road layout or supplementary panel affect the 'Must Turn Right or Left' sign?

The placement of the sign and any supplementary panels or arrows are critical. The sign is only applicable to the lane it is associated with, often shown by overhead arrows or lane markings.
