Your work schedule will coincide with that of many other people and it will not always be in your hands to modify it. But if you can, make slight variations in your routine, like going to work earlier than normal.
Plan alternative itineraries, making use of routes that, although they may seem longer, will be faster and will help to clear the highways.
Use technology to your advantage. The GPS of your mobile phone, or other applications, can provide you with useful information for your trip, such as your exact location, the forecast of traffic on various routes, the location of the nearest gas stations, the least congested routes, alternative routes, etc.
When you spot the traffic jam in front of you, slow down and before you get into traffic, try to locate an escape route using the means we've talked about. If you join the jam, it will be very difficult to get out of it.
But if you still got into the traffic jam, pay attention to the directions about what not to do when driving in the middle of heavy traffic congestion.
