Why is 4WD safer than 2WD in rainy weather?

[HenryFitz]

4WD vehicles are safer than 2WD in rainy weather for the following reasons: All four wheels of a 4WD vehicle have driving force, combining the stability of front-wheel drive with the agility of rear-wheel drive, thereby enhancing driving safety on wet or snowy roads. When encountering sharp turns or skidding on wet/snowy surfaces, the 4WD system can automatically control torque distribution between front and rear axles as needed to maintain driving stability and safety. 2WD vehicles differ significantly. With front-wheel drive on slippery surfaces, the front wheels must simultaneously handle steering and driving tasks. During sharp turns or wet/snowy conditions, the front wheels may momentarily lose traction, causing light steering or failure, creating hazardous situations. Rear-wheel drive vehicles are prone to oversteer during sharp turns or on wet/snowy roads, leading to fishtailing. Therefore, 4WD is considerably safer than 2WD on wet surfaces.
