Under what circumstance can a driver ignore traffic signals?

A driver can ignore traffic signals when a traffic officer is directing traffic because the officer's authority supersedes the traffic signals. This is an important safety measure, as officers can assess the situation and manage the flow of traffic in real-time, which may be necessary during unusual circumstances like accidents, road construction, or emergencies.

In other scenarios, such as during heavy rain, while conditions may require drivers to proceed with caution, they still must obey traffic signals. Similarly, turning left does not exempt a driver from following traffic signals; it requires the driver to yield and adhere to any signals or signs designated for that movement. Rush hour does not provide a reason to ignore traffic signals; rather, it typically necessitates more diligence in adhering to road rules to prevent accidents and ensure smooth traffic flow.
