Condition B Removal
Condition B-Removal
A heavy vehicle licence with a condition “B” restricts the licence holder to driving heavy vehicles fitted with automatic or synchromesh gearboxes only.
What is Condition B
A heavy vehicle licence with a condition “B” restricts the licence holder to driving heavy vehicles fitted with automatic or synchromesh gearboxes only. The licence holder is prohibited from driving vehicles with a non-synchromesh gearbox (also referred to as a Crash box).
Non-Synchromesh Gearbox
A non-synchronous transmission, also called a crash gearbox, is a form of manual transmission based on gears that do not use synchronizing mechanisms. They require the driver to manually synchronize the transmission’s input speed (engine RPM) and output speed (driveshaft speed).
When using half gears, the gear-shifting technique transitions from double clutching to a single clutch movement. In this process, the gear lever is moved either within the same gear position or to the next full gear, which you’ll explore more as you advance through the course.
What sets this gearbox apart is that the driver must synchronize the road speed (KM) and engine speed (RPM) to execute a gear change. These gearboxes require more driver involvement to ensure smooth or successful gear transitions. With each gear change, the clutch is engaged twice, giving rise to the term “double clutching.”
