Can you put an adapter on a dryer plug?
Answer: You can, and it will be wired the same way the article describes for a three-wire dryer cord. The biggest concern is the breaker size and the ampacity of the outlet; both should be 30 amp. If the breaker is larger than that, it won't provide the proper protection for the dryer or the wire.

Is it safe to use a dryer adapter?
The solution is to hire a local licensed electrician to install a new dedicated circuit and 4-prong outlet for your dryer so you can safely plug it in. A newer dryer run on a 3-prong system is an electrical hazard at best, even if nothing goes wrong, and a disaster if there is a short or loose wire.
Are 3 prong plug adapters Safe?
