What is a critical step when preparing for winter driving conditions?

Checking tire pressure and tread depth is crucial when preparing for winter driving conditions because proper tire performance significantly impacts vehicle safety and control in adverse weather. Cold temperatures can cause tire pressure to drop, and correctly inflated tires ensure better traction on slippery surfaces. Additionally, having sufficient tread depth is vital as it helps channel water and snow, reducing the risk of hydroplaning and improving grip on the road. By ensuring that tires are in good condition and properly inflated, drivers can enhance their ability to navigate through snow and ice, ultimately reducing the likelihood of accidents during winter driving.
