| Summary: | Dangerous driving behaviour among heavy vehicle drivers such as lorry
and busses often becomes a hot topic of conversation due to the danger it causes to
other road users such as speeding, especially in Jalan Batu Pahat-Kluang, which are
one of the most lethal highways in Malaysia. This highway has one of the highest
rates of accidents in Malaysia. Therefore, this study has been conducted on this
highway. This research will help to identify the type and rate of dangerous driving
among commercial vehicle and bus drivers as well as to determine the speed limit
compliance among commercial vehicle and bus drivers during morning and afternoon
at this highway. Video recording method has been used to obtained data before the
data is analysed using the mathematical formula such as Poisson Probability Method
and Hypothesis Testing. The Poisson Probability Method is applied to the data to get
the likelihood of committing dangerous driving. Hypothesis Testing will be used to
know the compliance of the speed limit, and t-test to test if the mean speed is equal
to or below the speed limit. The result of this study found out that speeding is the
most common type of dangerous driving that have an average of 76.92 vehicles per
hour at Km-15 while at Km-24.5, speeding is committed at an average of 65.67
vehicles per hour. Besides that, drivers at Km-15 and Km-24.5 does not comply to
