snow banks).
• A vehicle appears in the opposite lane while cornering or rounding a curve.
• When crossing a narrow bridge.
• When passing under a low gate or through a tunnel or narrow gate.

• If you suddenly come close to a vehicle ahead.
• When driving in areas where there is high grass or forage.
• Two-wheeled vehicles such as motorbikes or bicycles.
• Pedestrians or non-metallic objects such as standing trees.
