What does chocked mean?
Chocked is the past tense and past participle of the verb 'chock', which means to steady or immobilise something — most often a wheel — by placing a wedge or block against it. The practice is essential wherever vehicles or heavy loads might otherwise roll: aircraft are chocked on the tarmac as soon as they park, lorries are chocked during loading, and cars are chocked before being jacked up for repair. A 'wheel chock' is the small wedge-shaped block itself, typically made of rubber, wood, or plastic. The word belongs mainly to technical and safety-minded contexts such as aviation, shipping, haulage, and garage work, and its use signals care and proper procedure rather than any emotional tone. It should not be confused with 'choked', which describes blocked breathing or airflow; 'chocked' always involves a solid object physically preventing movement. Figurative use is rare, though the related expression 'chock-a-block' preserves the underlying idea of cramming something full.
Secured or supported with a chock or wedge, especially so that a wheel cannot move.
"The trailer was chocked with rubber blocks before the horses were loaded."
Almost always used in passive constructions ('was/were chocked') or with the wheels themselves as the subject.
Held securely in place by a wedge or block.
"Make sure the wheels are chocked before you climb under the vehicle."
One misplaced letter turns a blocked airway into a parked aeroplane: 'choked' stops your breath, but 'chocked' stops your wheels.

Etymology of chocked
The noun 'chock', from which 'chocked' derives, first appears in English in the late 17th century, originally in nautical use for a wedge or block used to secure cargo or prevent movement on board ship. Its further origin is uncertain, though some sources connect it to Old French 'çoc' or related Germanic words meaning a log or stump. The verb followed naturally from the noun, and the phrase 'chock-full' shows the same word family, conveying the sense of filled to capacity.
