Can the car still be driven when the differential lock light is on?

When the differential lock indicator light is on, the car should not continue to be driven. The following are the specific functions of the differential lock: 1. Improve passing ability: The differential lock is designed to enhance the car's ability to pass through bad road conditions. When one of the car's drive axles spins freely, it can quickly lock the differential, turning the two drive axles into a rigid connection. 2. Transmit torque: It transfers most or even all of the torque to the non-slipping drive axle, making full use of the adhesion to generate sufficient traction, allowing the car to continue moving. 3. Differential function: It prevents the vehicle from having one wheel spinning freely or being suspended while the other wheel spins, which would make the car unable to drive normally or get out of trouble.
The differential lock light came on while I was driving on a suburban road, and I suddenly noticed the yellow light flashing on the dashboard, which made me nervous. I remember the differential lock is a device used during off-roading to lock the wheels and help get unstuck. The light being on could mean it's engaged or there's a malfunction. The car was still drivable, but it felt very awkward on regular roads like city streets or highways. When turning, the car felt stiff, as if the rear wheels were locked, increasing resistance and accelerating tire wear. After driving about ten kilometers with the light on, I stopped to check and noticed some abnormal tire wear. Later, at the repair shop, the mechanic told me that prolonged driving like this could damage the differential components, leading to expensive repairs. So, my experience tells me that while the car can still be driven when the light is on, it's best to avoid sharp turns, sudden braking, and maintain low speed, and get it checked the same day.
As an experienced off-road enthusiast, I've encountered the differential lock light coming on several times. It usually means the lock is engaged, which is fantastic in mud or snow—improving wheel traction and ensuring proper power distribution. However, if the light stays on while driving on pavement, trouble arises: wheels fight each other, turning becomes stiff, tire wear accelerates, and the differential may overheat. Once, I accidentally hit the switch, drove half an hour on the highway with the light on, and later found differential damage—costing extra in repairs. My advice? If the light appears, first try disengaging the differential lock. If the light goes off, false alarm. If it persists, drive slowly to a service station. Avoid long-distance risks—safety first.
I was quite scared when I first encountered the differential lock light coming on shortly after I started driving. After asking a friend, I learned it's a device that locks the wheels, mainly for off-road use. When the light is on, the car can still be driven, but it's best not to mess around on city roads as it can easily cause loss of control during turns and damage components. I've tried driving with the light on during a turn, and the car felt very stiff. Just drive slowly to get it repaired, and don't delay too long, or a small issue could turn into a big one. Simply put, you can drive, but be cautious.
