I read on the Wikipedia page on the Sultan Iskandar Building that is used to enter Malaysia from Singapore via the Johor–Singapore Causeway (Google Maps) (formatting is mine):

• The immigration checkpoint has different checkpoints for bus passengers, bus drivers, lorries, motorcycles and cars. [...]
• At the customs checkpoint, 36 counters are designated for cars (20 for those arriving in Malaysia and 16 for those leaving the country) and 25 for motorcycles (17 for arrivals and 8 for departures).

Which immigration and customs checkpoints should one use when walking across the border from Singapore to Malaysia via the Johor–Singapore Causeway?
