Selecting your speed when going downhill is crucial for ensuring safety and maintaining control of your vehicle. The correct approach involves considering the weight of your vehicle and the current road conditions. Heavier vehicles, such as trucks, require more attention to speed as they have a greater potential for gaining momentum while going downhill. This increased weight can lead to longer stopping distances and a higher risk of losing control if speed is not carefully managed.

Additionally, road conditions play a significant role. Factors such as weather (rain, snow, ice) or the state of the road (steepness, sharp turns, poor surface) can drastically affect how well your vehicle performs. By accounting for these elements, you can select a speed that allows for safe navigation and adequate response to any hazards that may arise.

Previous experience and traffic conditions are important considerations but should not be the sole basis for speed selection on downhill slopes. Likewise, while observing speed limits is necessary, they do not account for the unique challenges presented by the incline and the specific characteristics of your vehicle. Thus, the most comprehensive and safest strategy is to adjust your speed based on both the vehicle's weight and the current road conditions.
