You are travelling on a narrow two-lane road and are approaching a child riding his bike on the right side of the road. A line of oncoming vehicles following a slow moving truck is approaching in the oncoming lane. You should flash your lights and tap your horn and: slow down and move closer to the truck

Explanation:

Change just a single lane at once. While switching to another lane to get ready for a turn, you should flag your goal to do as such at any rate 200 feet preceding evolving lanes or turning. Your sign separation must be in any event 300 feet before the turn in the event that you are working a vehicle in a speed zone of at any rate 50 miles for every hour.

Try not to zigzag all around lanes, which will significantly build your hazard of a mishap. On the thru-way, more slow vehicles should utilise the correct lane. Leave the left-hand lane for quicker moving or passing vehicles. Keep below principles when you are moving to another lane:  

Make sure that there is no traffic in front of you in the lane you might want to enter  Check your mirrors for any vehicles that are getting ready to pass you  Briefly turn your head toward the lane that you are entering to ensure that there is no vehicle in your vulnerable side and that there is adequate space to move into the adjoining lane  Use your blinker to caution different drivers of your goal to change lanesSmoothly move into the new driving lane
