What is locking your wheels?

Can you use it in a sentence? This could have multiple meanings.

Locking your wheels could mean braking so hard that the wheel stop turning even though the vehicle is still moving. e.g. skidding such as when on ice. "I stepped on the brake and my wheels locked up"

Or, if this is a 4WD vehicle, it could mean engaging the front wheels so they are connected to the rest of the drive train. Older 4wd vehicles had manual dials on each front hub that you would turn to either engage - or disengage that wheel to the transmission. When disengaged - that wheel would spin free like on a 2wd vehicle. When engaged, it now receives power from the transmission same as the rear wheels. Engaging a hub in this manner is called "Locking in the hubs" or "Locking in the wheels". BTW - most modern 4WD vehicles have an automatic locking mechanism that performs this task for you when you shift into 4WD.

Lastly, I suppose once could say "locking your wheels" is setting the parking brake so that the wheels cannot roll.
