Can your car handle this flood? Check MMDA's flood gauge first

Typhoon Carina and the strong southwest monsoon brought so much rain that many places were left with flooded roads, making it hard for people to go about their daily lives. The severity of the weather even forced Metro Manila into a state of calamity.

On July 24th, the situation required immediate action. The MMDA reported that in Manila the floods were shallow enough to manage, but in Quezon City, the waters rose to dangerous levels. The Marikina River, which often acts as a gauge for flooding, rose alarmingly, triggering multiple warnings and eventually an evacuation order.

This makes you think, doesn't it? How high did the water get near you, and what would you do if you faced that again? Floods can turn roads into rivers. Driving through floods can feel like a gamble. But what if you knew exactly how deep the water is? How much risk is too much when the streets turn into rivers? The MMDA flood gauge is here to guide you.

The shallowest water levels categorized by the MMDA, gutter to half-knee level floods, mean water depths between 8 to 10 inches. These conditions are generally considered safe for all types of vehicles. At this level, water does not typically pose a threat to the mechanical and electrical systems of most vehicles. However, continuous exposure to water can accelerate wear and tear on vehicle components like brakes and tires. Drivers should remain alert for sudden deeper pockets or hidden debris that could cause damage or loss of vehicle control.

Driving through these levels might seem less risky, but it’s important to maintain a slow speed to minimize water splashing into engine components. Regular inspections after driving through water can help catch and address any potential issues early, such as checking for water in the brake system or making sure that drainage plugs under the vehicle are clear to avoid water accumulation.

Floodwaters that reach from half-tire to knee level, covering 13 to 19 inches, present a more alarming threat, particularly for light vehicles which might experience water ingress in the engine bay. These conditions can stall engines and lead to costly repairs. Vehicles driving through these waters often require higher clearance and strong waterproofing around components like the engine air intake and electrical wiring.

For drivers in areas experiencing these water levels, avoiding travel until water levels recede is advisable. If travel is unavoidable, vehicles equipped with snorkels and sealed electrical systems offer better stability. Try to monitor the vehicle's performance closely during and after transit through these depths for early detection of any damage.

Driving through flood water that is waist to chest high, or 26 to 45 inches deep, is extremely hazardous and generally considered impassable for all types of vehicles. These depths can completely submerge cars and even float vehicles off the road, leading to dangerous situations. The force of the water at this height can also be a threat to the structural building of roadways and bridges, increasing the risk of accidents.

During such severe flooding, the only safe action is to avoid these areas completely. Vehicles should be relocated to higher ground well in advance of rising water levels. For residents in flood-prone areas, preparing a flood action plan including specified safe routes and contacts for emergency services is helpful for safety.

Knowing MMDA's flood levels can save your car and maybe even your life. Knowing how deep the water can get helps you make the right choices about driving during a flood. Always choose safety first, and remember, when in doubt, don’t go out.
