Tips

Yes—roof racks and roof tents are legal in the Philippines. But because you’ll be driving on public roads, the Land Transportation Office (LTO) has rules and limits that you will need to follow so your setup stays safe and compliant, especially if you are using aftermarket roof racks. 

This guide explains those rules so you know exactly what to do if you intend to use roof racks and tents—regardless if you’re a first-time car owner or a seasoned adventurer.

What Are Roof Racks and Roof Tents?

Roof racks are sturdy metal bars mounted on top of a vehicle to help carry big or bulky items that can’t fit inside the cabin. Roof tents, on the other hand, refer to the foldable camping tents designed to sit securely on top of a roof rack, giving travelers a safe and elevated sleeping space. Both are used to add extra room for gear, make trips more comfortable, and support outdoor activities like biking, camping, and surfing.

They also offer the following benefits:

• Lets you carry large items like bikes, surfboards, kayaks, luggage, or camping gear
• Frees up space inside the car for passengers
• Helps protect the interior from dirt, odors, and damage
• Allows you to bring a rooftop tent for camping without needing ground space
• Provides better organization during long trips

So, Are Roof Racks Legal?

Yes. But aftermarket roof racks must be registered with the LTO because they add weight and change the vehicle’s configuration.

Here’s a detailed guide for you:

• Registration required: Any roof rack that is not part of the vehicle’s original design must be registered as a Top Load Accessory.
• Where to register: At any LTO office or satellite branch, usually during your annual vehicle registration.
• Cost: Around ₱100–₱200 for the Top Load Permit.
• No registration needed for:
  • Roof rails that come standard with the vehicle (e.g., Toyota Fortuner).
  • Temporary or detachable bike racks used only on weekends and removed afterwards.
• Why it’s required: Adding weight on the roof changes the vehicle’s handling and height, especially when loaded.

Are Roof Tents Legal?

Yes. You can use a roof tent on public roads as long as the roof rack it sits on is properly registered.

Make sure to take note of the following:

• The tent itself doesn’t need registration. It is considered “cargo.”
• What matters is the rack. Your roof rack must have a Top Load Permit.
• Weight rules: Follow your vehicle manufacturer’s and rack manufacturer’s load ratings.
• Installation: The tent must be tightly secured and stable before driving.

Risks and Dangers

Using roof racks and tents also come with risks and dangers, hence the need for LTO regulation. Some of these risks are as follows:

• Too much weight on the roof can affect handling, braking, and stability
• Improper installation may cause the rack or tent to detach while driving
• Roof-mounted cargo increases wind drag, reducing fuel efficiency
• Added height may trigger higher toll classifications or hit low clearances
• Noise, vibration, and roof scratches can occur with some rack designs

LTO Rules You Must Follow 

In case you really need roof racks and/or roof tents, make sure to keep these in mind: 

Top Load Permit

• Required for aftermarket roof racks.
• Fee is around ₱100–₱200.
• Records changes in your vehicle’s weight configuration.

Weight Limit

• Maximum of 20 kg per square meter on your roof rack.
• Overloading can affect your vehicle’s balance and braking.

Safety and Dimensions

• Cargo must be secured firmly.
• Nothing should block the driver’s view or stick out dangerously.
• Secure all cargo using proper straps or mount systems.

Maintenance

• Follow weight limits and check your vehicle’s roof load rating.
• Remove temporary racks when not in use to avoid noise, drag, and unnecessary attention at expressways.

Why Some Cars Get Charged Higher Tolls

Some expressways classify vehicles as Class 2 if sensors detect a height above 7 feet—including items mounted on roof racks like bikes or cargo boxes, causing confusion for many riders and weekend bikers.

Skyway has addressed this by:

• Keeping Class 1 rates for vehicles with bike racks or boxes.
• Tellers taking photos of affected vehicles to balance the system later.

However, other expressways (like portions managed by MATES) still rely on automatic height sensors. This may explain why you get Class 1 going south, then Class 2 going north. This is a system limitation—not a penalty for using roof racks.

If you travel often or love outdoor adventures, using a roof rack or roof tent can make your trips easier and more fun. Just follow the LTO rules, keep safety in mind, and you’re good to go on any Philippine road.

Yes, you may lower your car, but extremely lowered cars that affect safety are not allowed on public roads. The Land Transportation Office (LTO) does not ban lowered cars outright or set a minimum height. However, any modification that affects safety or structural integrity can make your vehicle illegal for registration or road use. If the ride height change makes your car unsafe, unstable, or far from its factory parameters, it may be considered illegal for public roads and can be flagged during inspection.

In this guide, let’s take a closer look at what “extremely lowered” means, what the Philippine law says, and what steps you should take if you want to modify your car and use it legally and safely.

What is an Extremely Lowered Car?

An extremely lowered or slammed car is a vehicle whose ride height has been significantly reduced, often for aesthetics or performance purposes. This usually involves modifying the suspension, chassis, or other structural components. 

While lowered cars may look cool or handle differently on smooth roads, excessive lowering can:

• Reduce ground clearance and cause the car to scrape speed bumps, potholes, or uneven roads.
• Compromise suspension performance and braking.
• Affect vehicle stability, steering, and handling.
• Potentially damage the chassis or drivetrain.

Because of these safety risks, the LTO closely monitors heavily modified vehicles. 

What the Law Says

The main rule that covers lowered cars is Department Order No. 2010-32, which aligns with UN-ECE international safety standards. It doesn’t give exact measurements for ground clearance, but it clearly bans modifications that affect safety.

Some of the prohibited modifications detailed in this DO include:

• Axle modification
• Chassis modification
• Extended chassis/body
• Extended overhang
• Change of rim size
• Modification of handle bar or muffler
• Reconfiguration of body dimensions and design

These items matter because lowering often requires adjustments to suspension, wheels, bumpers, or chassis. If any of these fall outside safe or approved parameters, the vehicle can be marked unsafe.

Criteria for Flagging Lowered Cars

Because there’s no official minimum ground clearance, LTO inspectors have discretion. A car can be flagged if:

• It bottoms out easily on humps or uneven roads
• Suspension travel becomes unsafe
• Wheels rub on the body
• Handling becomes unstable
• It damages the road surface
• It no longer meets factory safety specs

The LTO states that tampering with suspension, drivetrain, wheels, and brakes outside approved limits may affect performance and put road users at risk.

Note: The LTO has not set an exact minimum ground clearance, so enforcement can be subjective. If a lowered car is judged unsafe or significantly outside manufacturer specifications, it will likely be considered illegal for public roads. Remember: Heavily modified vehicles are generally intended for racing tracks, not public roads.

Penalties

Extremely lowered cars considered unsafe by the LTO can lead to serious consequences such as:

• Fine: Php 5,000 for operating a car with unsafe or unauthorized modifications.
• Vehicle Impoundment: The LTO can impound your car at your expense. It will only be released after all safety defects are corrected, the vehicle passes inspection, and fines are paid.
• Correction of Defects: Owners must fix unsafe modifications, such as extremely lowered suspension, to restore roadworthiness according to LTO standards.

Even if a modification looks minor, if it affects handling, stability, or road safety, it may be considered illegal which can result in fines or impoundment.

If you’re a rider you need to know that you need a motorcycle with at least 400cc engine displacement to be legally allowed on the expressways. Anything below this is not allowed, no matter the brand, model, or appearance. This rule comes from the Limited Access Highway Act (Republic Act 2000) and DOTC Department Order No. 2007-38, which set the standards for who can safely use high-speed roads.

Many riders get confused or frustrated because they want faster travel, smoother roads, and safer routes—but the law is firm. Expressways are designed only for vehicles that can safely keep up with higher speeds and traffic flow. This guide explains everything you need to know so you know exactly what to expect and how to stay safe and compliant while riding your motorcycle. 

 

Understanding Motorcycle Displacement and Expressway Requirements

Motorcycle displacement refers to the size of an engine’s combustion chamber, measured in cubic centimeters (cc), and it indicates how much air and fuel the engine can burn to produce power. Motorcycles 400cc and above generally have stronger engines, higher top speeds, and better stability at fast highway conditions, while those 399cc and below may struggle to keep up with expressway traffic, which is why the government restricts them for safety. This requirement started decades ago when expressways were developed, and authorities needed a clear, measurable benchmark—engine displacement—to decide which motorcycles could safely travel alongside faster, bigger vehicles.

Why the 400cc Rule Exists

The 400cc rule comes from both the Limited Access Highway Act (RA 2000) and the DOTC Department Order No. 2007-38, which were created to regulate who can use high-speed, limited-access roads based on performance and safety standards. These laws give the DOTC/DOTr and toll operators the power to regulate which vehicles may enter expressways.

The law was created to keep riders safe on roads where vehicles travel fast and there are:

• No pedestrian crossings
• No loading or unloading
• No intersections
• High-speed through traffic

Motorcycles below 400cc may struggle to maintain safe speeds or react quickly in fast-moving situations, which puts the rider and other motorists at risk. 

Expressway Rules

Even if your motorcycle meets the 400cc minimum requirement for using the expressway, you must still follow these rules:

• Maximum of one back rider only
• Both rider and back rider must wear helmets
• Must follow all speed limits
• No lane splitting or overtaking between lanes
• Must use normal lanes like other vehicles
• Headlight must always be on
• Tail lights and signal lights must be working
• Only normal saddlebags or approved luggage carriers allowed
• Must have valid registration and a valid driver’s license
• Must present documents upon request
• Must pay Class 1 toll rate

Violating these rules may result in penalties under Section 10 of RA 2000.

Vehicles Not Allowed on Expressways (At Any Time)

The law was also clear that the following cannot use the expressway at any time:

• Motorcycles below 400cc
• Scooters below 400cc
• Tricycles
• Bicycles
• Pedestrians
• Overloaded or unsafe vehicles

Reminders 

The TRB has repeatedly reminded everyone of the rules on riding motorcycles and using the expressways. Some of these reminders are as follows:

• Toll operators must strictly block sub-400cc motorcycles.
• Fake decals do not count—only official LTO records determine displacement.
• RFID should not be issued to sub-400cc motorcycles.
• Misdeclared registration documents may lead to legal action.

If you are a rider, here are some other reminders you need to keep in mind before attempting to use the expressways:

• Check your motorcycle’s official displacement on your LTO registration.
• Do not rely on stickers, labels, or assumptions.
• Only ride on expressways if you meet the 400cc minimum and the rules above.
• Stay updated and ride safely.
