Is it mandatory to reduce your speed in poor weather conditions?

In situations involving poor weather conditions, the law generally requires drivers to adjust their speed to ensure safe driving. Therefore, the assertion that one can "always drive at maximum speed" is not in alignment with safe driving practices and legal expectations.

Adhering to safe speed limits is critical in adverse weather, as reduced visibility, slippery surfaces, and other hazards necessitate a more cautious approach. This means that regardless of the exact weather conditions, such as rain, snow, fog, or ice, drivers must evaluate and adjust their speed accordingly to maintain control over the vehicle and respond effectively to changing conditions.

The requirement to drive at a speed that is reasonable and prudent for the existing conditions is a fundamental principle of traffic safety laws, reinforcing the necessity to lower speed during poor weather, thus promoting safety for all road users.
