在Woodroffe路上的一个小学门口看到的,一直不明白是什么意思,有懂的吗?科普一下呗。
 
A no engine braking road sign warns truck drivers against using the engine to brake. Truck drivers normally downshift the engine to slow the truck down without applying the breaks.

Engine brake normally referrs to the truck drivers downshift the gears with the manual transmission to slow the truck down without applying the breaks. This action usually produces a loud noise. I used to do it in the highway downhill with my manual Ford about 30 years ago.
 
Google 一下就知道engine brake的噪声了。
