Guam traffic and driving

When you are driving on Guam

Because there are no trains on Guam, the main means of transportation is cars.  It is recommended to use the shuttle buses around the shopping centers and the hotels. Shuttle buses provided by optional tours such as ABC will take you to the optional tour specific location. Taxi and car rental are other ways of transportation.


Attention when walking on a sidewalk

  • Let’s always walk in the direction opposite to the direction of the car.
  • For safety at night, walk with two people(or more) and walk in places with plenty of traffic and bright places.
  • Let’s use a crosswalk with a signal when crossing the road.
  • In the case of a push-button type signal, you can cross if the display is walking.  If it is blinking, it will be a red sign soon. Let’s pass quickly.  In the case of hand shaped display, it means red light and crossing should not be done.
  • When crossing the traffic lights at the intersection, be careful of turning cars.

Shuttle bus

There is a shuttle bus that connects Tumon, Tamuning, Agana village (Hagatna) area, etc.  The shuttle bus that connects shopping points operates frequently, so if you are doing things around the hotel area, mainly in the area of ​​Tumon, Tamuning, Agana (Hagatna), you will rarely feel inconvenienced by using shuttle buses.

Tickets for the shuttle bus are sold at the tour desk in the hotel, in the Guam airport, at the ticket booth set up at the shopping centers. Even if there is no ticket in advance, you can also purchase it from the driver at the time of getting on.

Driving in Guam

Rules and cautions in driving

In Guam, cars drive on the right hand side of the road center line, with the car having a left side steering wheel. The position of the signal levers and the wipers are attached to the reverse of a Japanese car.

Speed ​​is displayed in miles and 1 mile is about 1.6 km, the speed limit is about 15 miles per hour (about 24 km to 40 km) in the city area and 35 miles per hour (about 56 km) in the suburbs. Pay attention to and follow signs of speed limit.

From the end of March 2012, the use of mobile phones while driving is prohibited. As in Japan, contact with police or fire department for hands-free use or emergency, parking in a safe place is permitted by law. Please note that offenders will be fined 100 US dollars or more.

Wearing a seat belt while driving is required. Please keep in mind that rules on child safety seats as follows.

School bus

You should not overtake the school bus when it stops. A car behind the bus has to stop at the back until the school bus continues moving forward. Please wait patiently. Furthermore, you must also stop for the bus if you are in the oncoming lane. This rule will not change even on a wide road like 3 lanes on one side. If you overtake or pass by a bus without stopping you will be fined for a traffic violations.


When the sign of STOP is open like this ,let’s stop and wait.


Intersection without signal

At intersections without traffic lights, cars arriving at the intersection first take precedence. Please note that there is no rule such as right turn priority or straight run priority

Right Turns

Except when there is a sign of “NO (RIGHT) TURN ON RED”, you can turn right at a red light if you pause. Even when turning right is possible, there are pedestrians in the crosswalk so take care before turning right.


Center middle line usage

This lane is a lane for turning or U-turns once after entered in the middle and you have temporarily stopped. Then turning or making a U-turn can be done safely. Since it is not a driving lane, running straight through this lane is very dangerous. When turning left, make sure that there is a signal exclusively for left turn, and if there is a signal exclusive for left turn, do not turn left until the signal for turning left turns green even though straight ahead light is green.。

Guam road

On some parts of Guam’s road there is a road mixed with corals, and on rainy days it is very slippery so let’s drive safely.

Manners peculiar to Guam

In Japan there are people who turn off the headlight at the signal light waiting, but never turn off the headlights on Guam. It is a traffic violation.

How to put gasoline into your car

There are various kinds of gasoline as follows, but most gas stations are handled as “Regular”, “Plus / Super”, “Super / Premium”.
Basically it is “Regular (Regular)” gasoline that is used when renting a car and putting in gasoline.
Depending on the gas station, it is written as “Unleaded / Extra” or “Unleaded Plus / Supreme”

Putting in gasoline and paying

The gas station is divided into self-service and full-service machines. As with Japan, self-service is less expensive. Park your car next to the refueling machine on the side of your cars gas tank.


Go to the cashier and tell the number of the refueling machine and the type of gasoline you want. Pay a deposit (advance payment). In other words, if you want to add regular $10.00 for a refueling machine No. 5, say “Number Five. Regular Ten dollars please”. If you want to fill regular with a No. 5 refueling machine, say “Number Five. Regular Full It Up Please”. After telling the number of the refueling machine, the type of gasoline and the amount of gasoline to be filled in, return to the refueling machine outside.




Insert the nozzle into the filler neck and squeeze the grip to start refueling. When the payment amount becomes full, the sound will be heard and the fueling will be slowed down, then stopped. When you hear a clicking sound, return the nozzle and close the filler cap. (In the case of a type in which the lever of the base of the pump nozzle is raised up to release the lock, the base is lowered and the pump nozzle is returned to its original position)


Go to the cashier and tell the number of the refueling machine and settle payment. Refueling is completed after receiving the change deducted from the money paid as the deposit.

 Drunk driving

If arrested for drunk driving, in addition to detention for at least 2 days and a fine of US $1,000.00, other penalties may be imposed.
