Do hazard lights conflict with turn signals?

Hazard lights and turn signals do not conflict. Below is relevant information about automotive lighting: Basic introduction: Automotive lights are various traffic lights installed on vehicles to ensure safe driving, divided into two categories: illumination lights and signal lights. From 1905 to 1912, to address road illumination ahead, acetylene headlamps with spotlights began to be installed, accompanied by a kerosene lamp as the rear license plate light. By 1945-1947, the minimum required external lighting fixtures had been finalized. Qualified automotive lights must comply with corresponding photometric, colorimetric, and basic environmental test specifications; Development trends: Irregular-shaped headlamps that align with streamlined vehicle body designs will continue to evolve, and high-intensity discharge lamps may become the new generation of headlight sources; Research is ongoing to improve high-mounted brake lights and high-contrast combination rear lights.
I've been driving for decades and often encounter conflicts between hazard lights and turn signals. This is because, in vehicle design, they typically share the same set of bulbs and control circuits. When the hazard lights are activated, the system prioritizes processing the hazard warning signal, temporarily occupying the turn signals. For example, after a tire blowout on the highway when I turn on the hazard lights to warn others, if I suddenly need to turn right at an exit, the turn signal won't light up at all. This can lead to misjudgment by drivers behind me, increasing the risk of a rear-end collision. I've experienced several such awkward moments in the past. Now, I've learned my lesson: when the hazard lights are on, I simply pull over safely before making any turns to avoid operating in dangerous situations. Although some new cars have intelligent systems that reduce these conflicts, most older vehicles are like this, so I have to rely on myself to pay extra attention to safe driving habits.
When I first got my driver's license, I didn't understand why the turn signals stopped working when the hazard lights were on. After checking the manual, I realized the bulbs are shared, and the hazard lights override the turn signals when activated. Once on a snowy day with slippery roads, I turned on the hazard lights and drove slowly. When I tried to change lanes for a left turn, the signal wouldn't light up, and the car behind almost hit me, giving me a cold sweat. The main reason for this conflict is that the circuit design prioritizes cost savings and simplicity, giving emergency situations higher priority. As a new driver, I now remember not to use turn signals when the hazard lights are on. If I need to change direction, I first turn off the hazard lights for a few seconds, complete the maneuver, and then turn them back on. This helps reduce misunderstandings and keeps both myself and others safe.
