The main purpose of the UA99 sign is to provide advance warning of a potentially hazardous intersection where accidents have occurred frequently. It prompts drivers to adjust their speed, increase awareness, and prepare for a situation that may require extra caution or a change in driving behaviour.
Upon seeing the UA99 sign, you should immediately begin to prepare for the intersection ahead.

Yes, you should avoid treating the UA99 sign as mere decoration and waiting until the hazard is directly upon you. Furthermore, avoid overtaking or making sudden lane changes in the vicinity of the warning, as these actions can significantly reduce your safety margin in a situation already identified as risky.
A common trap is for learners to believe the warning is only relevant when visibility is poor. However, the UA99 sign indicates inherent risk due to the intersection's design or traffic patterns, requiring a general increase in caution regardless of immediate visibility. Another trap is not preparing early enough, waiting until the last moment to slow down.
No, the UA99 sign itself does not mandate stopping or automatically give way. It's a warning about a generally hazardous location. Your obligation to stop or give way will depend on the specific traffic control at the intersection (e.g., traffic lights, stop signs, priority rules) and the actions of other road users. The sign simply advises you to be extra prepared.
