Ay, going to add a bit more here.
Most snakes don't look to encounter humans. The problems humans face with snakes usually arise due to accidental encounters or human actions towards the snake so both of these problems can be managed from the human side.
What snakes are in your area? Are they venomous or non-venomous, or a mix of the two? Have you spent some time looking at images of the snakes in your area to enable you know the type of snake should you encounter one? What are the specific habits of the snakes in your local area? All this knowledge can help you to avoid them or keep safe should you encounter one.
Snakes hear differently from humans, they lack external ears. However, they can hear through their inner ear via their jawbone, and what they hear are vibrations. Thus, having a heavy footfall as you walk will help to alert a snake you're coming, allowing it to slither off in the opposite direction. This inability to hear in the same way that we do can be used to your advantage, as you can alert your fellow humans that you have come across a snake without any concern that your talking will aggravate it.
For the most part, snakes like places like under rocks, on ledges, in trees, inside hollow logs, under wood piles and in shrubs. They can also be found in water both land and water based snakes can swim. They can easily be overlooked for leaf litter, sticks and plant materials. This is why you are at greater risk of encountering a snake when going off-path and into thick vegetation. The human defensive skill when walking amid potentially dangerous wildlife is vision and whenever human sight is reduced, the risk increases. One example of a snake that relies on its camouflage over moving out of the way is the Australian death adder. It will often remain coiled up, relying on the leaf litter as camouflage. This is why you must not rely on vibration alone, but also use sight (look for coiled, round shapes in this instance), while you could also gently prod through vegetation with a large stick before heading across it. This is yet another reason why you need to be aware of what type of snakes are in the area and their typical habits.
Things to watch for can include. The snake curls itself up, in some snake species, this can be a sign it is getting ready to strike. The snake raises its head, When done in reaction to an encounter, it is a fairly good indicator that the snake is getting ready to strike. Striking distance of a snake is generally about half the snake's body length but you should give the snake at least double that length of space between you and it. Moreover, this is dependent on the snake type, hence the need for learning more about the snakes in your area.
Wear the appropriate clothing, especially for your feet and legs. Ninety percent of snake bites are focused on the ankle area, so it makes sense to cover up these parts of your body. This means wearing long pants and boots. Since a snake's bite instinctively clamps on, if it gets nothing more than pants, you may avoid a bite on your skin. Looser pants also allow for better airflow that cools you in warmer weather (the weather you're more likely to encounter snakes in). Thick socks are an extra layer of protection, provided you can stand them if it's hot. Don't rely on clothing alone, as it is just one part of your whole line of defensive actions. There is no guarantee a snake won't bite through clothing.
Also snakes will naturally gravitate towards warm roads and pathways when these have residual heat as darkness falls because this helps them to keep warm.
