Looks like you forgot to close the if statement.

you caught me while updating.

Where are you referring to? as I see all ( ) are closed?

All you need is an end after the line with return "safe".

def check_speed(car_speed)
  if (car_speed > 39) && (car_speed <= 50)
    return "safe"
  end
end

Ah! thank you for the set of eyes as I was looking at the end, not thinking I needed two. Simple mistake. appreciate it.

No worries! It's easy to overlook, especially since many languages allow you to not close if statements when only a single line is present. The "ruby way" to achieve this would be to put it all on one line:

def check_speed(car_speed)
  return "safe" if (car_speed > 39) && (car_speed <= 50)
end

But sometimes that can be hard to read, so it's a judgement call.
