Authorities are urging motorists to slow down and be cautious, especially when driving during foggy conditions. That’s after an Arab man died and seven others were injured when a truck collided with a bus transporting workers on Abu Dhabi-Al Sila Road on Sunday morning. Investigations have been launched to determine the exact cause of the accident. Abu Dhabi Police have called on drivers of heavy vehicles to postpone travel until the fog clears up. They also recommended that drivers avoid tailgating, switching lanes or overtaking during periods of low visibility.
