Shuay or Heng??

Today around 1715,a accident happend in my workplace..

I gantry my tt and hit a prime mover(pm),my wheel guard is totally damage..
Thing happend under my known..I dunno how does it happend until another pm driver told me that i hit a pm chasis that not suppose to stop in my gantry path..After i hit it,the pm run off..Technician come and take off the wheel guard and inform me i have to park my tt into the servicing bay..Then i go to write statement..After i finish the statement,around 2030 i go home..

Shuay is accident happend,but i don't think i got resposible on it because the pm driver can't stop at the gantry path..But i still got a bit worry i still "kena"

Heng is i can go home early..It's been a long time i never go back early..Quite happy but hopes i won't "kena" anything..
