How many hours of bus ride will have a toilet break? Here is my experience:
KL to Cameron Highland. 4.5 hours. 1 toilet break.
Ipoh to KL. 4 hours. 0 toilet break. I was suffering.
If I take 5 hour ride, how many toilet break?

Things get worst when..

It is raining and the bus air con still full blast, and you forgot to bring jacket..

But actually you can ask bus driver to pull over for a short stop if you really cannot tahan...

From Subang to Singapore, 1 stop as well. Between 5 - 6 hours.

will kena marah by the driver.

Experienced once before. Sohai driver go die la.

Singapore - KL one stop iirc

y la suffering ?
u can ask the driver to stop la for the smoke/toilet/stretch break.

then u shud diau dia balik ma.

Pee on driver to show dominance

I nvr get scolded by driver before. but he give me death stare only.

I tell him, I sakit perut..mau berak...

Kalau terkeluar, busuk satu bus lagi susah kan.

prepare rubber band or empty mineral bottle

Aeroline First Class Shuttle

One of the few operators in Malaysia offering a washroom on board, specifically in their lower‑deck business lounge. It’s a double-decker coach—upper deck for seating, lower deck lounge with toilet and pantry, and served by cabin crew  .

Travelers consistently confirm Aeroline as the only major Malaysia–Singapore or JB–KL bus operator with onboard toilets

Same thing happened to me. Chee Bye drivers. Waited 4 hours in the bus for him to start the journey to Kedah at KL. After that detour to Ipoh to drop off passengers. When I ask him for a toilet break in Kuala Kangsar he show his angry face. To wait 10 minutes for toilet break he cannot tahan but as passengers we wasted 1/2 a day for him to collect enough passengers. Malay driver terrible service.

this is one of those very weird things about malaysia
usually only 1 break or zero break

but overseas long distance bus, they stop every 1-2 hours
because they know we got needs and we're just humans...meanwhile local long distance bus never thought of that

yeah
in EU it the law, bus running time got record
bus driver have to stop 40min after 4 hours driving. can split break time.
daily drive time cant exceed 9hour.

Ipoh Amanjaya to KL Sentral on Easter Sunday 2018 took nearly 7.5 hrs, highway was super-jammed. 3 rest stops. Ever since then i booked ETS tickets extra-early to avoid having to use the bus.

Go for business class bus with toilet built in

Never been to the camrin. The bus ride nice?

KL - JB / SG got 1 stop. Causeway Link and KKKL.

Others hamkaling I don't know and can fuck right off

This is probably the only time this is the right answer

Just pee on the floor.
