Words by Ben Stower

Business travel can take us all over the world. Although travel provides many enjoyable moments, one of the most stressful experiences in life can be driving in another country.

Getting behind that wheel, and even organising a set of wheels, can be a tough learning curve to throw into an already busy work trip.

But there's no need to stress, not when you have an expert's guide on the renting and driving rules and regulations in some of the most popular cities for Australian business travellers.

First tip out of the blocks: Book online. Using an online booking provider will make life easier. The process is simple, letting you choose the car class, rental company and pick-up/drop-off location. The best also let you pay in Australian dollars.

New York, USA

Renting

Cost at counter: About $140 per day

Budget options: Thrifty, Budget, Alamo and Dollar.

Luxury options: Avis and Enterprise.

Drop-off fee: Expect to pay a drop-off fee if you don't return the car to the same store where you picked it up.

Tolls: New York City is inundated with tolls, in tunnels, over bridges and on the highways. If you don't have an E-ZPass you'll need to pay each toll with exact change. Avoid the stress and add an E-ZPass to your booking if you think you'll be encountering a lot of tolls.

Fuel: Approximately $0.79 per litre.

Minimum age of driver: 18 (additional surcharges to be paid unless you're 25 or older)

Car advice: New York City can be a tough driving environment. If you're nervous it's best to opt for a larger vehicle that sits you above the traffic, such as an SUV.

Driving

Rules to consider:

• Driving on right side of road.
• No right on red – In many USA cities and towns it's possible to turn right at an interesection even if the traffic light is red. However, this rule does not apply in the state of New York to cities with more than one million residents. Certain signs may permit it in NYC, but when in doubt, wait until the light turns green.
• Slow drivers to the right – There are no overtaking lanes in New York. Instead, in the case of a multi-lane road, slow drivers are required to stick to the right-most lane. This allows faster drivers space to go around.
• An International Driving Permit is recommended, but not required.

London, England

Renting

Cost at counter: About $200 per day.

Budget options: Sixt, Budget, Alamo and Europcar.

Luxury options: Avis, Enterprise, National and Hertz.

Fuel: Approximately $2.31 per litre.

Minimum age of driver: 21.

Car advice: With the price of fuel around the city so high and England's notoriety for small lanes and tight parks, it's best to opt for a small car with high fuel economy.

Driving

Rules to consider:

• Driving on left side of road.
• Sequence of traffic lights – The UK includes a red + amber light before green to make sure drivers are ready to go, but you can't move until the green light.
• It's illegal to use your mobile phone with the engine running even if the car is stationary, unless it's hands-free.
• Anyone driving a vehicle in Central London between 7am and 6pm, Monday to Friday, needs to pay the Congestion Charge or risk being fined. This can be pre-paid online for the reduced price of $20 per day. Street signs indicate where the Congestion Charge zone begins and ends.

Cost at counter: About $120 per day.

Budget options: Thrifty and Budget.

Luxury options: Avis and Hertz.

Tolls: Singapore's Electronic Road Pricing system (ERP) manages road congestion by charging drivers for using priced roads during peak hours.

Drivers without a CashCard will be charged a minimum of $10.

Fuel: Approximately $2.15 per litre.

Minimum age of driver: 20 (varies between companies).

Car advice: Singapore law requires all drivers on the road to have Third Party insurance cover. Make sure this is added to your booking.

• Designated speed limits – Singapore has three speed limits for cars: 50km/h on roads; 70-90km/h on expressways; and 50-80km/h in tunnels.
• The legal Blood Alcohol Content for drivers is 0.08 per cent.
• Headlights must be turned on between 7pm and 7am.

Cost at counter: About $60 per day.

Budget options: Thrifty, Dollar, Keddy, Budget and Europcar.

Luxury options: Avis, Hertz, Firefly and National.

Mexico City, Mexico

Renting

Cost at counter: About $60 per day.

Budget options: Mex, Right Cars, America Car Rental, Hertz, National, Sixt and Europcar.

Luxury options: Budget, Avis, Alamo and Thrifty.

Tolls: Toll roads are relatively sparse in Mexico, but you may encounter some if you need to venture outside Mexico City. Keep an eye out for signs reading 'cuota', as this means toll road, while 'libre' means free road. At the moment cash is the preferred form of payment.

Fuel: Approximately $1.06 per litre.

Minimum age of driver: 25 (some exceptions, but a younger driver must pay expensive surcharges).

Car advice: Double check that the mandatory liability insurance is included in the rental price. If it isn't, you may have to pay twice as much.

Driving

Rules to consider:

• Driving on right side of road.
• Make sure you always slow down for topes (speed bumps), as these can damage your car if taken at speed.
• Some driving signals in Mexico have multiple meanings – A left-side indicator could mean the driver is turning left or it's okay to pass them.
• An International Driving Permit is recommended, but not required.

Hong Kong

Renting

Cost at counter: About $100 per day.

Budget options: HAWK.

Luxury options: Avis and Hertz.

Tolls: There are certain tunnels and bridges around Hong Kong that will charge drivers for using them. The cost varies from HK$3 for Tseung Kwan O Tunnel to HK$30 for the Lantau Link. Payment can be made with cash or credit card.

Fuel: Approximately $2.68 per litre.

Minimum age of driver: 21 (surcharges for drivers younger than 25).

Car advice: Make sure it is absolutely necessary for you to rent a car in Hong Kong. With the high price of fuel, parking and rental, coupled with busy roads and periods of intense congestion, having a private car can often be more trouble than it's worth.

Driving

Rules to consider:

• Driving on left side of road.
• Silent zones – When you are driving in a silent zone you are only allowed to use your horn as a warning, not a rebuke. Signs indicate when silent zones start and finish.
• An International Driving Permit is recommended, but not required.
