hahaha...forgot to brake..straight jump to conclusion thought it was personal vehicle
personally test using my car,northbound found that the safe limit is 180 due to road condition and not much straight road. southbound is the best, 200+ is possible. The limit is on my car chassis/aero la.
Anyhow, those were done at past midnight,dry road but at past midnight the risk is wild animal cross the road, however in the morning pulak, lory tyre scattered here and there, some are very big chunk.
simple blackbox for lorry driver can be done. just put a gps,weight sensor and maybe inspection schedule, wont cost much,even build one for final year in UNI last time. But when G involve, everyone want the piece of the pie.
Very old lorry still on the road, Saw one at nkve last week. Then one with wooden cabin/door. carrying heavy load
