Driving requires substantial focus.
And the last thing we need is confusion.
One common observation on highways is confusing placement of two similar
"DO NOT ENTER. WRONG WAY"
signs on the entry area of the highways. There is usually an entry lane and an exit lane on the same road.
The signs are meant for the exit lane.
The first sign is placed correctly to the left of the exit lane.
But alas! the second sign is placed on the right side of the exit lane - which at first seems correct, BUT the entry lane of the highway happens to be on the right side of the second sign, thus sending a ambiguous signal to the driver to not enter the highway using the entry lane.
A quick way to correct this mistake is to remove the second sign since it is not necessary.

Another confusing observation are traffic lights placed a distance away at the convergence of 2 angled (around 45 degree apart) converging roads. At times, it is not clear which light is for which road - since one must be red and the other green for safety purpose. And sometimes the 2 sets of light for the 2 roads are built into the same box, possibly increasing more confusion.
The solution is to have separate traffic posts well placed directly in front of the stop zone, thus immediately visible to the driver.

I recently encountered another situation that a traffic light is not placed in front of my car, but to the right side of the road.
Although that light is visible, it is still a dangerous placement. We are used to seeing the traffic light in front of us - that is how our eyes scan for those lights NATURALLY- thus one could overlook and not be aware of it if it is suddenly place to the right of the road ( not sure if this is legal DOT wise ).
