When should you switch into a lower gear while driving downhill?

Switching into a lower gear before you start moving downhill is crucial for maintaining control of your vehicle and managing speed effectively. By downshifting in advance, you allow the engine to assist in braking, which reduces the reliance on brake systems and minimizes the risk of brake overheating. This technique enhances stability and helps prevent the vehicle from accelerating too quickly as gravity pulls it down the slope.

In addition to improving control, engaging a lower gear early allows for smoother transitions as you descend, helping to manage your speed more consistently. This proactive approach is vital for safety, especially when navigating steep or extended downhill grades. It's important to be in the appropriate gear ahead of time so that you're prepared for any changes in road conditions or traffic ahead.
