Bangladesh Driving Rules for Americans
Bangladesh drives on the LEFT. Urban limits are 40 km/h (Dhaka) to 60 km/h, highways 80–100 km/h. BAC limit is 0.05%. Carry your US license, IDP, and passport at all times.
Rules are set by the Bangladesh Road Transport Authority (BRTA) under the Road Transport Act 2018.
1. Left-Side Driving — The Biggest American Adjustment
Bangladesh inherited UK colonial-era driving conventions. This is the single largest learning curve for US drivers.
- Traffic flows on the LEFT. You drive on the left side of the road; you overtake on the right.
- Steering wheel on the right of the vehicle. Pedals are in the same order (clutch–brake–gas left to right).
- Roundabouts run clockwise. Yield to traffic already in the circle, entering from your right.
- Turn signals and wipers are reversed from US cars. Expect to flick the wipers when turning for the first few days.
- Mental rule: When making any turn, the driver (you) should end up closer to the centerline. If you're heading toward the curb, you turned wrong.
2. Speed Limits in Bangladesh
Limits are set by the BRTA and posted in km/h. Enforcement is mostly via Highway Police speed checks rather than fixed cameras.
| Road Type | Limit (km/h) | Equivalent (mph) |
|---|---|---|
| Dhaka city (central) | 40 | ~25 |
| Other urban areas | 50–60 | ~31–37 |
| Rural roads | 60–70 | ~37–43 |
| National Highways (e.g., N1, N5) | 80 | ~50 |
| Dhaka–Chittagong Expressway / Padma Bridge link | 100 | ~62 |
| School/hospital zones | 20–30 | ~12–19 |
In practice, Dhaka rush-hour speeds rarely exceed 15 km/h regardless of the posted limit. Highway limits are the ones to actually watch — Highway Police use radar.
3. Alcohol & Mobile Phone Rules
Blood Alcohol Concentration (BAC)
The legal limit is 0.05% BAC, but in practice Bangladesh is largely a dry country. Alcohol is restricted to licensed hotels, diplomatic clubs, and a small number of permitted outlets for non-Muslims and foreigners. Driving with any alcohol in your system is a bad idea — penalties under the Road Transport Act 2018 include heavy fines and potential imprisonment for serious cases.
Mobile Phones
Hand-held mobile use while driving is illegal. Hands-free (Bluetooth, speakerphone with the phone mounted) is permitted. Fines for hand-held use are typically Tk 500–1,000 (~$5–$10) but vary by jurisdiction.
4. Seatbelts, Helmets, and Child Safety
- Seatbelts: Mandatory for front-seat occupants. In practice often ignored by locals — but enforced more strictly for foreigners and on highways. Fine: ~Tk 500.
- Helmets: Mandatory for both motorcycle rider and pillion passenger.
- Child seats: Not legally required in private vehicles, and rarely available in rentals. If traveling with young children, consider bringing your own portable car seat.
- Number of passengers: Cars cannot exceed manufacturer capacity. Overloading is common locally but enforced against foreigners.
5. Road Signs — Bangla and English
Major highway and tourist-area signs are bilingual (Bangla + English). Rural roads are often Bangla only. Learn these basics:
| Bangla | Transliteration | English |
|---|---|---|
| থামুন | Thamun | Stop |
| প্রবেশ নিষেধ | Probesh nishedh | No Entry |
| গতি সীমা | Goti shima | Speed Limit |
| বিদ্যালয় | Bidyaloy | School |
| হাসপাতাল | Hashpatal | Hospital |
| পেট্রোল পাম্প | Petrol pump | Gas Station |
| এক মুখী | Ek mukhi | One Way |
Standard international symbol signs (red triangle warnings, red circle prohibitions, blue circle mandatory) are used everywhere and look identical to US signs.
6. Police, BRTA, and Enforcement
You'll interact with three main authorities:
- Dhaka Metropolitan Police (DMP) Traffic Division: Manages signals, intersections, and most stops in Dhaka. They wear navy uniforms with white traffic gloves.
- Bangladesh Police Highway Patrol: Patrols inter-city national highways (N1 Dhaka–Chittagong, N2, N5, N8, etc.). Use radar and roadblock checks.
- BRTA (Bangladesh Road Transport Authority): The regulatory body — they handle licensing, vehicle registration, and policy. You won't typically interact with them as a tourist.
- Mobile Court: A magistrate sits roadside (often at busy intersections or during enforcement drives) and issues on-the-spot fines with legal authority. Always demand an official receipt (rosid).
At a checkpoint, slow down, lower your window, keep hands visible, and present US license + IDP + passport copy. Polite, calm, smile. English is widely understood in Dhaka; less so on rural highways.
7. The Horn Culture and Lane Discipline
Two things about Bangladesh traffic genuinely shock first-time visitors: the volume of honking and the apparent disregard for lane lines.
- Honking is communication. A short beep means "I'm here, on your right/left." Two short beeps means "I'm overtaking." A long blast means "Move." It's not road rage.
- Lane lines are advisory. Three-lane roads frequently carry five rows of vehicles. CNGs and motorcycles fill every gap. Hold your line, signal, and expect aggressive but slow-speed merging.
- Right of way is informal — generally goes to whoever commits first. Eye contact and small lane-position shifts signal intent. Defensive driving is essential.
- "No-Honk Zones" exist near hospitals and some VIP areas in Dhaka, marked by signs. Honking here can earn a Tk 500 fine.
