Malaysian highways have a speed limit of between 90 to 110km/hour. Our highways here are well-maintained and during non-peak times such as non-festival periods, it's indeed very enjoyable to drive along it. Going slow is definitely not the order of the day. Most vehicles would be breaking the speed limit cutting down travel time.
As radar detectors are not allowed to be sold here, many vehicle-owners resort to buying them online or buy them whenever they travel overseas.
