Travel in Kuala Lumpur
The roads of Kuala Lumpur aren’t the best place to drive. So unless you have your local host driving with you, you might want to consider a different method for getting around. Signs can be confusing, traffic sits still during rush hours, and some drivers are dangerously reckless. Taxis aren't bad, just try to get them to use the meter. Stay clear of taxis during rush hours, and remember to negotiate hard.
The best way to travel in Kuala Lumpur hands down is to take the trains. The train system is sufficiently developed, cheap, and the few different lines cover most of the parts of the city you'll be visiting. Not all trains are part of the same network, so sometimes you'll have to buy multiple tickets, and if it rains you might get wet when transferring between lines. Taking the trains during rush hour might be difficult as the trains will be packed to the brim and fighting your way in and out of the vehicle can be quite a hassle, however it is still a better option than being stuck in traffic jams.
