# Usability of Certain Symbols Indicating Automobile Safety Status Based on Youth Assessment
### Safety Symbols Used in This Research
Transmission oil temperature (according to ISO 7000-1168B standard [23])  
The transmission oil temperature symbol provides information on whether the transmission system is functioning correctly and alerts the driver when the transmission oil is overheating. Overheating can cause significant damage to the transmission system, which can be expensive to repair. The transmission oil temperature indicator helps to identify potential issues before they become major problems. 8. Steering failure (according to ISO 7000-2441 standard [24])  
The dashboard of an automobile also contains a warning indicator in the form of a steering failure symbol, which serves to alert the driver to any potential problems with the steering system. The symbol usually looks like a steering wheel with an exclamation point or some other type of cautionary sign. It is important to take immediate action when the symbol appears on the dashboard in order to avoid any further damage to the steering system. If the necessary steps are not taken, it can lead to a lack of steering control, which can be particularly hazardous when traveling at high speeds. This can cause serious safety risks and should be avoided at all costs. _9. Loose wheel warning indicator_  
This warning symbol is designed to alert the driver that one or more of the wheels are loose or not properly secured. Several factors can affect the activation of the loose wheel warning symbol indicator. Loose lug nuts or bolts due to improper installation or wear and tear can cause this warning symbol to appear. Checking for this warning symbol can help drivers maintain their vehicles and ensure their safety on the road. _10. Electric park brake trouble indicator_  
The electric parking brake system is in charge of automatically activating the parking brake when the vehicle comes to a halt, and it also prevents the vehicle from moving when parked. If the electric park brake warning symbol is turned on, it usually indicates a problem within the system that requires attention. This could be due to a malfunctioning switch, a faulty wiring connection, or a problem with the brake actuator. In some cases, the indicator may also be illuminated if the parking brake has not been fully released before the vehicle is driven. If the electric park brake trouble indicator is illuminated, the driver should take the vehicle to a qualified mechanic for diagnosis and repair. _11. Brake fluid level (application of ISO 7000-1401 standard [25])_  
The brake fluid level symbol is an indicator on the dashboard of automobiles that is used to indicate the amount of brake fluid in the vehicle's brake system. This symbol is typically a circle with a wavy line running through it. The line is usually red and indicates that the brake fluid level is low. A low level of brake fluid can cause the brakes to fail. _12. Antilock braking system trouble_  
A safety feature commonly found in contemporary vehicles, the antilock braking system (ABS) aids drivers in maintaining control during emergency braking circumstances. By utilizing sensors to identify when a wheel is on the verge of locking during forceful braking, the ABS system automatically adjusts brake pressure to avert wheel lock-up. When the ABS system is malfunctioning, a warning symbol will appear on the dashboard of the vehicle. If this warning light appears, it is important to have the ABS system checked by a qualified mechanic as soon as possible. _13. Lambda sensor warning indicator_  
A lambda sensor warning symbol on a car's dashboard serves as an alert for the driver regarding a potential issue in the vehicle's exhaust system. Also referred to as an oxygen sensor, the lambda sensor is an apparatus that measures the oxygen levels present in the exhaust system. As part of the vehicle's emissions control system, it ensures that the vehicle runs efficiently while producing minimal emissions. If the lambda sensor identifies an issue, it transmits a message to the car's computer, causing the lambda sensor alert symbol to appear on the dashboard.
