How should stickers be applied to a vehicle?

1. From the outside

2. From the inside

3. On the windshield

4. On the bumper

The correct answer is: From the inside

Applying stickers to a vehicle from the inside is essential for ensuring that they remain protected from the elements and that they adhere properly without the risk of peeling or exposure to external factors. This method safeguards the sticker from weather conditions such as rain, snow, and UV rays, which can lead to fading and deterioration over time. Additionally, internal application ensures that stickers do not obstruct the driver’s view or violate any legal requirements regarding visibility and safety. When considering the other options, applying stickers from the outside may lead to potential damage, such as peeling due to exposure to weather and debris. Placing them on the windshield could obstruct the driver’s view if not positioned correctly, which can create a safety hazard. Similarly, while stickers on the bumper might be permissible, they can be more susceptible to physical damage and may not comply with regulations if they obstruct any required markings or lights. Thus, placing stickers inside the vehicle provides the most practical and compliant solution.
