What is the action required if a maximum speed sign indicates 90 km/h?

• A. Maintain a speed of 90 km/h at all times
• B. Adjust your speed based on road conditions
• C. Speed up to reach 90 km/h immediately
• D. Only drive at 90 km/h on highways

Answer: (B)

A maximum speed sign indicating 90 km/h sets a legal limit, but it's important to recognize that driving conditions can vary significantly due to factors such as weather, traffic, road conditions, and visibility. Therefore, the appropriate action in response to this sign is to adjust your speed based on these conditions.

For instance, if the road is wet or icy, it may be safer to drive below 90 km/h to maintain control of the vehicle. Similarly, in heavy traffic or poor visibility, reducing speed might be necessary to ensure safety. The emphasis is on prioritizing safety by adapting your driving speed according to the prevailing conditions, rather than strictly adhering to the sign without consideration of these factors.

Maintaining a speed of 90 km/h at all times does not take into account the variation in conditions that could necessitate a slower pace. Likewise, speeding up to reach 90 km/h immediately would not be a safe choice if conditions are poor. Finally, the idea that driving at 90 km/h applies only on highways is misleading, as the limit applies wherever the sign is posted, regardless of the road type. Hence, adjusting speed based on road conditions is the best and safest approach.
