Quick summary
A private car with a licensed driver covers the 230 km Phnom Penh–Sihanoukville expressway route in about two hours for $50–70, against three hours and $10–15 by expressway bus. Day rates run $50–70 for a sedan, $70–100 for an SUV and $90–120 for a van, typically 8–10 hours, with fuel and tolls usually included.
The catch: since 11 May 2026 an International Driving Permit alone no longer lets you self-drive in Cambodia — you must convert to a temporary Cambodian licence. This article compares every current option and the safety cautions that are actually sourced.
Since 11 May 2026, driving yourself in Cambodia has required converting your home licence and International Driving Permit into a temporary Cambodian licence. An IDP alone is not accepted, according to the Department of Public Works and Transport in Phnom Penh. That change removes the simplest answer for anyone weighing how to travel between Phnom Penh and Sihanoukville. A short trip now comes with a licence-conversion errand that most visitors would rather avoid.
The other choices have changed, too. Passenger rail has returned, but direct flights have stopped. A hired driver’s value now rests less on speed than on door-to-door routing and verification.
For travelers from North America, Europe and Australia, the question is narrower than ‘is Cambodia safe’. It is whether a hired driver is the safer and better-value choice on this corridor, what the daily rate buys, and which sourced cautions apply to a trip that stays on the expressway.
What runs now on the Phnom Penh–Sihanoukville corridor
Planning guides list four ways to cover the 230 kilometres. Only three run on any given day.
Passenger rail operates only on weekends, according to Cambodia’s Ministry of Public Works and Transport. No source gives a start or end date for that restriction: weekend-only is the current schedule, not a phase with a known finish.
The former 45-minute direct flight no longer operates. The remaining air options involve indirect routings that take longer and cost significantly more. Air travel is effectively off the table for this corridor.
On the ground, the expressway has changed the arithmetic. Expressway buses take about three hours and cost $10–15, according to route reporting.
A private car with a driver covers the same distance in roughly two hours for $50–70, according to route reporting. When buses took five to eight hours, a private car bought you half a day. Now it buys about sixty minutes.

How safe are private drivers in Cambodia?
Cambodia safety guidance recommends hiring a licensed local driver through a reputable provider for intercity travel. It describes this arrangement as safer and more predictable than finding transport on the street or driving yourself.
Petty theft and bag snatching, rather than violence, are the main safety concerns reported for tourists. Phnom Penh and crowded areas are particular concerns.
The difference is verification.
A vetted agency or a ride-hailing app leaves a record of who drove you and what you agreed to pay. A kerbside negotiation does not. That record is the practical difference between a private driver and a stranger with a car.
What a private driver costs and includes
Cambodian driver rates are quoted per vehicle, per day. They are usually all-inclusive. A sedan runs $50–70 a day, an SUV $70–100, and a van $90–120. The typical day lasts 8–10 hours.
The package normally covers the car, the driver’s fee, fuel for the agreed itinerary and road tolls. It also covers the driver’s own food and accommodation.
Long-distance one-way hires are priced separately. Siem Reap to Phnom Penh with a car and driver runs $90–130 one-way, with fuel and tolls normally included. Tipping is customary but not obligatory, at roughly $3–5 per day for a driver.
For a group, the extra cost buys door-to-door routing and about an hour less on the road. For two travelers, the private car stops looking like a bargain.
Self-drive, ride-hailing and the current license rule
Rental companies set their own minimum ages, generally between 21 and 25. Some require at least 25.
Self-drive also looks cheaper than it is.
A car without a driver runs roughly 30–40% below a chauffeured rate, but fuel is added separately. One-way hires can carry a small return fee for the driver, and airport pickups often attract a surcharge.
Ride-hailing fills the short-hop gap. Grab listed 21 Cambodian markets as of August 2026. PassApp operates in seven cities with tuk-tuks, rickshaws, cabs and SUVs. Airport-to-city fares run about $10–20.
For trips longer than a city hop, the app model and the hired-driver model converge: both provide a licensed driver, a known vehicle and a fare agreed in advance. Getting out of Phnom Penh’s airport without a taxi scam applies the same skill to a shorter trip.
Where the real sourced safety cautions are
The Thailand border carries a specific warning. The UK’s safety and security advice for Cambodia and other 2026 guidance advise avoiding travel within 50 kilometres of it because of conflict and landmines. Cross-border land crossings may be closed. Siem Reap, Phnom Penh and Battambang are unaffected by that tension, so the standard tourist circuit lies outside the affected strip.
Unexploded ordnance remains a genuine hazard, but the risk is confined to rural, off-path areas in the northwest. There is no active landmine risk on standard tourist paths.
Petty-crime hotspots named in safety guidance include riverside areas such as Sisowath Quay, the area around Wat Phnom, and BKK1. Incidence is higher at night. This is a phone-and-bag problem rather than a personal-safety one: it follows you on foot, not in transit. Bag snatching in Phnom Penh is almost always a passing-motorbike crime of opportunity.
What to confirm before you book the car
The booking you would have made in 2025 is not the booking to make now. Two of the four options on this corridor changed within the past year.
- Verify the driver and vehicle with the agency or app before departure: confirm the driver holds a Cambodian licence and the car is registered, and keep that confirmation in writing. Settle the all-inclusive rate and a no-night-driving rule before departure.
- Split the group deliberately. A van at $90–120 a day is $22.50–30 per person for four, roughly double the expressway bus fare. A sedan at $50–70 is $25–35 each for two. Below three travelers, the expressway bus at $10–15 wins on price.
- Set up the app before you land. PassApp has had SMS verification problems with foreign numbers, so verify your account before arrival. Grab’s vehicle options vary by market.
- Watch: whether direct Phnom Penh–Sihanoukville flights return. Any resumption would change the time-and-cost calculation on this corridor.
Keep valuables secured rather than visible, carry a copy of your passport instead of the original, and share your itinerary with someone at home. Avoid isolated areas at night, and stay on paved roads and marked trails rather than cutting across fields. Travel insurance should include medical evacuation cover.
For the trip to Sihanoukville, these details are easier to settle at a desk than at a kerb. Confirm the rate, the driver and the hours in writing.

What licence do I need to drive myself in Cambodia?
Since 11 May 2026 you need more than an International Driving Permit. Self-drive requires converting your home licence and IDP into a temporary Cambodian licence, issued through the Department of Public Works and Transport in Phnom Penh; an IDP alone is not accepted. Rental companies also set their own minimum ages, generally 21 to 25.
How old do you have to be to drive in Cambodia?
Rental companies set the floor rather than a single national age: minimums generally fall between 21 and 25, and some companies require at least 25. Confirm the minimum with the specific agency before you book, because it varies by operator and vehicle type.
Is it safe to use Grab or PassApp in Cambodia?
Both are price-transparent app bookings rather than street negotiations, which is the main safety advantage. Grab listed 21 Cambodian markets as of August 2026 and PassApp covers seven cities, but PassApp has had SMS verification problems with foreign phone numbers, so register and verify before you arrive. Airport-to-city fares run about $10–20.
What is included in a private driver’s daily rate?
The usual all-inclusive structure covers the car, the driver’s fee, fuel for the agreed itinerary, road tolls and the driver’s own food and accommodation. Tipping is customary but not obligatory, roughly $3–5 per day. One-way hires and airport pickups can carry small extra fees.
Do I need to worry about landmines in Cambodia?
Not on the standard tourist circuit. Unexploded ordnance remains a hazard in rural, off-path areas of the northwest, but there is no active landmine risk on standard tourist paths, and Siem Reap, Phnom Penh and Battambang are unaffected by the border tension 50 km from Thailand. Stay on paved roads and marked trails.
