While a left-hand blind turn...
While a left-hand blind turn restricts your view less than a right-hand bend and allows you to take more of a conventional line, be especially wary of tightening your line to the point that your head may be over the center line.
The same hillside that makes a turn blind is often the source of gravel in that turn; likewise, the same trees that make a turn blind usually drop leaves or moisture on the road. A blind turn and a slippery surface often go together. This is where things can get tricky as with a wide line you don't have much room to straighten up and ride directly over something. The upside is that the wide line has let you see the slippery bit earlier than you would have otherwise and given you time to adjust your line. When you do come upon gravel or something slippery on the road, momentarily tighten your line and arc toward the inside of the corner. It may seem counterintuitive, but this will give you room to then straighten up and ride directly over the obstacle. Another danger in right-hand turns is that a wide entry leaves you more exposed to an oncoming car or bike that may be partly in your lane. The same applies to oncoming traffic as it does to gravel in the road: You should be going slow enough that you can momentarily tighten your arc to give you as much room as possible, then when the traffic is past return to your planned line.
Once you've gone down a particular road a few times, you'll be familiar with the blind turns and know a bit more what to expect. You'll know which turns are typically dirty or clean, and which corners tighten up. It's best to keep using that wide line on the left-hand turns, leaving you extra room should a car or bike be coming over the center line, but in right-handers a more conventional line and slightly tighter entry will give you more of a buffer to that oncoming traffic. Still, keep your speed down in case there is something unexpected to maneuver around.
Blind turns cause anxiety...
Blind turns cause anxiety because you want to look far down the road but can't, and this confuses your brain much as this picture does. Focus more than you would normally on what you can see, so that you are ready to react immediately to debris or oncoming traffic in your lane.
By far the majority of blind turns on the street are that way due to an obstruction that you can't see around. Occurring less frequently are corners made blind by the crest of a hill, and these are tackled in a slightly different manner. Your lane position has no effect on how far around the corner you can see, so keeping a wide entry doesn't help in that regard. In these situations the general rule is keep to the right, leaving as much of a buffer as possible to oncoming traffic. In left-hand turns this means the same approach and reduced speed as used in a turn made blind by an obstruction. In right-hand turns, keeping far to the right leaves you better positioned to simply straighten up over debris in the road as well as being less exposed to oncoming traffic. It may seem a lot to keep track of for the different turns, but thankfully much of your entry line will be intuitive, and you'll find yourself gravitating to the correct spot and slowing down the necessary amount anytime you can't see where you're going.
More than anything, it's the surprise of a car or patch of gravel suddenly appearing that can cause the most grief in a blind turn, especially with inexperienced riders. The shock can easily upset your concentration when you need it most. We've seen riders spooked by an oncoming car enough that they bobbled, straightened up and ran right off the road - luckily missing the car. In any blind turn, keep focused on where you're going, be ready for whatever may be on the other side of the turn, and have some speed and room in hand to account for it.
